Can somebody explain to me how 4sin2θ = (sinθ)^2 become 8sinθcosθ = (sinθ)^2 ?
1 answer
recall sin (2A) = 2sinAcosA
so 4sin2θ
= 4(2sinθ cosθ)
= .....

Can somebody explain to me how 2(u^2)(sin2θ)/g = (u^2)(sinθ)^2/(2g) become 4sin2θ = (sinθ)^2?
Top answer:
2(u^2)(sin2θ)/g = (u^2)(sinθ)^2/(2g) multiply both sides by 2 g 4 u^2 sin 2θ = u^2 (sinθ)^2
