Changing the subject of the formula into v means expressing v in terms of the other given variables. So given the original equation, as shown below, we can rearrange it so that we have v isolated on one side.
To isolate v, we can just multiply s to both sides and come up with the final equation below.
Thus, we have v = s(1 - F/f) with v as the subject of the formula.
Answer: v = s(1 - F/f)
To isolate v, we can just multiply s to both sides and come up with the final equation below.
Thus, we have v = s(1 - F/f) with v as the subject of the formula.
Answer: v = s(1 - F/f)

<h3>What is Trigonometry?</h3>Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
1. (cos x. cos y)(tan x + tan y) = sin (x+ y)
(cos x. cos y)(tan x + tan y)
= cos x. cos y (sinx/ cos x + sin y/ cos y)
= sin x cos y + sin y cos x
= sin (x+ y) [ sin ( x +y)]= sin x cos y + sin y cos x
= RHS
3.
Using identity
cos ² x=0
Applying then x=0
So, cos x =0
General solution will be .
