Find the exact value under the given conditions
1) tanx=-7/24, x lies in quadrant 2, cos(y)= 3/4, y lies in
quadrant 1
Find: sin(x+y), cos(x+y), tan(x+y)
2) cos(x)=21/29 x in quadrant 4, sin(y)=-5/12, y in quadrant
3
Find: cos(x+y)
First find the value sinx,siny,cosx,cosy,tanx,tany and then apply the formula
please do upvote ? if yo find my solution helpful in any way
This motivates me to help students in best possible way
Thank you?
