Question

If cosØ= 2x/1+x² find the values of sinØ and tanØ in terms of x.​ with explaination​

Answer 1

Answer:

sinA=(x²-1)/(x²+1)

tanA=(x²-1)/2x

Step-by-step explanation:

I will consider theta as A because it is easy to type.

cosA=2x/1+x²

sinA=opposite/ hypotenuse

=BC/AC

=x²-1/1+x²

= x²-1/x²+1

tanA=opposite/base

=BC/AB

=x²-1/2x

Hope it's helpful!!!
