Firstly, we must use the special property of trig functions which means that (sinx)n is the same as sinnx. Likewise, (cosx)n=cosnx, (tanx)n=tann...
Firstly let's expand out the staring equation getting rid of any brackets. This gives: 2-2cos(x)) = 3sin^2(x). Now we can spot that the sin^2(x) term is in the first equation but no the final one. So let'...
Solution: Parametric Differentiation with utilisation of Chain Rule.By the chain rule: dy/dx = dy/dt * dt/dxNote: dt/dx = 1 / (dx/dt)So dy/dt = 0, dx/dt = 3at^2So dy/dx = 0 * 1/(3a...
You can solve a cubic by applying factor theorem. This is where you plug different values for x into your cubic f(x) = ax^3 + bx^2 + cx + d such that x is a factor of d, until you find a value t for which...
This question requires integration since the area under the curve is equal to the integral between these bounds. Initially let u=3x-2 and differentiate with respect to x so then du/dx = 3. Rearrange to dx...
