Question

if tan a= x/y
then find sin a and cos a​

Answer 1

Answer:

Step-by-step explanation:

tan a=opp side/adjacent side

=x/y

sin a=oppside/hypotenuse

cosa=adjacentside/hypotenuse

hypotenuse=srt(x^2+y^2)

so

sin a=x/srt(x^2+y^2)

cos a=y/srt(x^2+y^2)

Answer 2

Answer:

Sin A = x/√x^2 + y^2

Cos A=y/√x^2 + y^2
