Question

find the exact value of each expression. tan(sin^(-1)(x/2))

Answer 1

let u=sin^(-1)(x/2)
so
sin(u)=x/2
draw right triangle

Answer 2

you will need to find the adjacent side using Pythagorean theorem

Answer 3

then you can find tan(u) and you will be done

Answer 4

Ok thanks very much. I understand now

Answer 5

did you want me to check your answer?

Answer 6

is it x/(4-x^2)?

Answer 7

almost

Answer 8

did you put a sqrt( ) on the bottom of all that one junk

Answer 9

x/sqrt(4-x^2)

Answer 10

so if I put the sqrt the answer is correct
