Solve the following: sinx - cosx = 0 for 0≤x≤360

We know that sinx/cosx = tanx. Therefore we can write sinx - cosx = 0 as sinx = cosx . By diving both sides by cosx, we get tanx = 1. By taking tan inverse of both sides, we can see that for 0≤x≤360, we get ...

Solve the following quadratic equation for X: X^2 -10X + 24=0

We can factorise the quadratic equation by noting that two numbers which multiply to get 24 and that add to get -10 are: -6 and -4. Therefore, we get (X-6)(X-4)=0 and we can solve for X to get X = 6 or X = 4.

a ball is dropped from rest off a cliff of height 50m, determine the final velocity of the ball assuming no air resistance.

Consider the appropriate equation of motion to solve this (use SUVAT method). The equation v^2=u^2+2 a s is appropriate to solve. Substituting in the knowns gives v=+sqrt(2 9.81 50)=31.32 which, quoted to th...
