Integration by parts:u = x u' = 1v' = Cos3x v = (Sin3x)/3 + cSo, ∫xCos3x= (XSin3x)/3 - ∫(Sin3x)/3 dx= (XSin3x)/3 - 1/3( - (Cos3x)/3) + c = (XSin3x)/3 + (Cos3x)/9 + c
I have written "..." where I imagine the student is replying. I have then provided prompts assuming that the student did not come up with the answer straight away. The scenario could be very...

Find out the value of the y coordinate where x=2y=3/(5-3(2))^2=3Differentiate function in order to find the gradient of the graph at point Py=3/(5-3x)^-2Use chain rule where u=5-3xdu/dx=-3dy/dx=3u^-2Hence...
When you start your A Level, radians can seem very daunting because you've never seen them before and pi seems a very confusing number to use in relation to angles. But trust me, if you embrace radians th...
