WebFinding the tangent formula follows the same method, either going through substitution into the sine and cosine formulas, or more directly, by making tan (-B) = - tan B. Either way you get: \displaystyle \tan (A - B) = \frac {\tan\ A - \tan\ B} {1 + \tan\ A\ \tan\ B} tan(A−B) = 1+tan A tan Btan A−tan B Ratios through the four quadrants WebFind sin (A+B) if cos (A) = 3/5 and sin (B) = -4/5 and A is in QI and B is in QIII. using identities: sin (A+B) = sin (A)cos (B) + cos (A)sin (B) plugging in what we know we start with: sin (A)cos (B) + (3/5)* (-4/5) = sin (A)cos (B) - 12/5

Step 1: Compare the cos (a - b) expression with the given expression to identify the angles 'a' and 'b'. Here, a = 90º and b = 30º. Step 2: We know, cos (a - b) = cos a cos b + sin a sin b. Also, we know that cos 60º = 1/2. Therefore the result is verified.
