WebDec 31, 2024 · cosine is 5/13 --> adjacent = 5 and hypotenuse = 13; then opposite is 12 So then sin (A) = 12/13, cos (A) = 5/13, and tan (A) = 12/5 Regarding angle B: sine is -12/13 --> opposite is -12 and hypotenuse =13; then adjacent is -5 So then sin (B) = -12/13, cos (B) = -5/13, tan (B) = 12/5 WebStep 1/3. Solution: Given sin A = 4 5 with A in quadrant I. We know that in quadrant I all trigonometric function is positive. So, cos A = 1 − ( 4 5) 2. => cos A = 1 − 16 25. => cos A = 3 5. And tan A = sin A cos A = 4 5 3 5 = 4 3. 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 rother levels
