Find all possible values of θ for tan θ = 2 sin θ with the range 0◦ ≤ θ ≤ 360◦

First you rearrange the equation.It is known that tanθ=sinθ/cosθ therefore if we replace tanθ with sin/cos we get:sinθ/cosθ=2sinθIf you multiply both sides by cosθ this becomes:sinθ=2sinθcosθThen if you m...

Find both stationary points for y= 4x^(3)-3x^(2)-60x+24. Also find the nature of those points.

y= 4x3- 3x2- 60x+ 24dy/dx = 12x2- 6x- 60 = 2x2- x- 10 = (2x-5)(x+2)
So stationary points are at x= 5/2 and x= -2
d2x/dy2 = 24...
