## sarihmanlapaz 2 years ago If ysinx=a and ycosx=b find y in terms of a and b. :)

1. akash_809

$y^2\sin^2x+y^2\cos^2x=a^2+b^2$------->$y=\sqrt{a^2+b^2}$

2. akash_809

since $\sin^2x+\cos^2x=1$

3. akash_809

do u get it

4. akash_809

@sarihmanlapaz do u need any further explanation...or u understand this

5. sarihmanlapaz

yes i get it! thanks for the help :)
