If sinA=3/5 and sinB=12/13, find the values of:
i) sin(A-B)
II) cos(A+B)
III) cos(A-B)
IV) tan(A+B)
V) sin(A+B) +cos(A-B)
Vi) sin(A+B)-cos(A+B)
Vii) cos(A+B)- cos(A-B)





Here, to solve these question, we first find out the values of sin, cos and tan at respective angles using the Pythagoras theorem.
Then, we use the formula of compound angles.
You need to understand these given formulas to solve these questions.



This is how you solve the Trigonometric Ratios of Compound Angles in Trigonometry of Mathematics.
