Question

If A and B lies in 1st Quadrant of such that sin A = 8/17 and cos B = 12/13. Find the value of sin (A-B).

Answer 1

Answer:Trigonometric values

Step-by-step explanation:

sinA=8/17

cosA=✓1-(8/17)^2=15/17 (sin^2(x)+cos^2(x)=1)

Similarly,sinB=5/13

cosB=12/13

sin(A-B)=sinAcosB-cosAsinB

Substitute values,you will get 21/221 as the answer.

Answer 2

Answer:

Trigonometric values

Step-by-step explanation:

sinA=8/17

cosA=✓1-(8/17)^2=15/17 (sin^2(x)+cos^2(x)=1)

Similarly,sinB=5/13

cosB=12/13

sin(A-B)=sinAcosB-cosAsinB

Substitute values,you will get 21/221 as the answer.
