Here, we have two functions, \( u(x) = x^2 \) and \( v(x) = x + 1 \), multiplied together. Applying the product rule, which states \( (uv)' = u'v + uv' \), we first find the derivatives of \( u(x) \) and \( v(x) \). The derivative of \( u(x) = x^2 \) is \( u'(x) = 2x \), and the derivative of \( v(x) = x + 1 \) is \( v'(x) = 1 \). Substituting these values into the product rule formula gives us \( f'(x) = (2x)(x + 1) + (x^2)(1) \), which simplifies to \( f'(x) = 3x^2 + 2x \).
To further illustrate, let's break down another example step-by-step: Differentiate \( f(x) = (x^3 + 2)(x^2 - 1) \). Here, \( u(x) = x^3 + 2 \) and \( v(x) = x^2 - 1 \). First, find the derivatives: \( u'(x) = 3x^2 \) and \( v'(x) = 2x \). Applying the product rule, \( f'(x) = (3x^2)(x^2 - 1) + (x^3 + 2)(2x) \). Expanding and simplifying, we get \( f'(x) = 3x^4 - 3x^2 + 2x^4 + 4x \), which further simplifies to \( f'(x) = 5x^4 - 3x^2 + 4x \). This step-by-step approach helps students in singapore junior college 1 h2 math tuition to grasp the mechanics of the product rule effectively.
As students progress in their H2 Math studies, they will encounter more complex polynomial functions. These might involve higher powers of \( x \) or more terms within each function being multiplied.

Tips for Mastering Combined Differentiation
So, you're tackling H2 Math in JC1, and the product rule is giving you a bit of a headache, leh? Don't worry, many Singaporean students find it tricky at first! This section will specifically look at how the product rule applies when you're dealing with trigonometric functions (like sine and cosine) and exponential functions (like ex). Mastering this is crucial for acing your exams and getting the most out of your singapore junior college 1 h2 math tuition.
Just a quick reminder, the product rule states that if you have a function y = u(x)v(x), then its derivative is:
dy/dx = u'(x)v(x) + u(x)v'(x)
In simpler terms, it's (derivative of the first function) times (the second function) PLUS (the first function) times (derivative of the second function).
Let's see how this works with trigonometric functions. Suppose you have a function like this:
y = x * sin(x)
Here, u(x) = x and v(x) = sin(x).
So, u'(x) = 1 and v'(x) = cos(x).
Applying the product rule:
dy/dx = (1) * sin(x) + (x) * cos(x) = sin(x) + x*cos(x)
See? Not so scary lah! Let's try another one:
y = cos(x) * x2
Here, u(x) = cos(x) and v(x) = x2.
So, u'(x) = -sin(x) and v'(x) = 2x.
Applying the product rule:
dy/dx = (-sin(x)) * x2 + (cos(x)) * 2x = -x2sin(x) + 2x*cos(x)
Fun Fact: Did you know that trigonometry has its roots in ancient astronomy? Early astronomers used angles and ratios to map the stars and predict celestial events!
Now, let's tackle exponential functions. Remember that the derivative of ex is simply ex. This makes it quite manageable with the product rule.
Consider this function:
y = x2 * ex
Here, u(x) = x2 and v(x) = ex.
So, u'(x) = 2x and v'(x) = ex.
Applying the product rule:
dy/dx = (2x) * ex + (x2) * ex = 2xex + x2ex = ex(2x + x2)
Another example:
y = sin(x) * ex
Here, u(x) = sin(x) and v(x) = ex.
So, u'(x) = cos(x) and v'(x) = ex.
Applying the product rule:
dy/dx = (cos(x)) * ex + (sin(x)) * ex = ex(cos(x) + sin(x))
Things can get a little more involved when you mix trigonometric and exponential functions, but the principle remains the same. Just take it step by step!
Example:
y = ex * cos(x)
u(x) = ex and v(x) = cos(x)
u'(x) = ex and v'(x) = -sin(x)
dy/dx = (ex) * cos(x) + (ex) * (-sin(x)) = ex(cos(x) - sin(x))
Interesting Fact: The number 'e' (Euler's number), the base of the natural logarithm, appears in many unexpected places in mathematics and physics, from compound interest calculations to describing radioactive decay!
Mastering differentiation is more than just knowing the product rule. It's about understanding various techniques and when to apply them. For your singapore junior college 1 h2 math tuition, focus on these key areas:
The chain rule is your best friend when dealing with composite functions like sin(x2) or e3x. The rule states that if y = f(g(x)), then dy/dx = f'(g(x)) * g'(x). Basically, you differentiate the outer function, keeping the inner function the same, and then multiply by the derivative of the inner function. So, if you want to do well in singapore junior college 1 h2 math tuition, you've got to get this down!
When you have a function that's a fraction, like (sin(x))/x, the quotient rule comes into play. In the Lion City's high-stakes academic landscape, parents devoted to their children's excellence in numerical studies frequently prioritize grasping the organized development from PSLE's fundamental issue-resolution to O Levels' intricate areas like algebra and geometry, and further to A Levels' higher-level ideas in calculus and statistics.

For authoritative information and resources, checking out the Ministry Of Education page can provide valuable information on regulations, syllabi, and educational approaches adapted to local criteria. Engaging with these authoritative materials enables households to align home learning with school expectations, nurturing long-term success in math and further, while remaining updated of the latest MOE programs for holistic pupil development.. If y = u(x)/v(x), then dy/dx = [v(x)u'(x) - u(x)v'(x)] / [v(x)]2. Remember the order – it's (bottom times derivative of top) MINUS (top times derivative of bottom), all over the bottom squared.
Sometimes, you'll encounter equations where 'y' isn't explicitly isolated, like x2 + y2 = 25. In these cases, use implicit differentiation. Differentiate both sides of the equation with respect to 'x', treating 'y' as a function of 'x'. Whenever you differentiate a term involving 'y', remember to multiply by dy/dx.
History: Isaac Newton and Gottfried Wilhelm Leibniz are both credited with independently developing calculus in the 17th century. Their work revolutionized mathematics and science, laying the foundation for much of modern technology!
With consistent practice and a solid understanding of these techniques, you'll be differentiating like a pro in no time. Remember to seek help from your teachers or consider singapore junior college 1 h2 math tuition if you're struggling. Jiayou!
