A ball is launched upwards at 30 degrees to horizontal with a velocity of 20 metres per second, how far does it travel before landing? (no air resistance)

Vertcal component of velocity: 20Sin(30) Rearrange suvat equation for t in terms of u, a, s t is the time in the air and is what we want, u is 20sin(30), a is -9.81 (negative since gravity pulls the ball dow...

Find the indefinite integral of sin(2x)(cos^2(x)) with respect to x.

We know from trigonmetric identities that cos(2x) = 2cos^2(x) -1, therefore cos^2(x) = 0.5(1+cos(2x)). Subbing this in gives the following integrand: 0.5(1+cos(2x))sin(2x). We can now split the integral into...
