WebStep 1: Use trigonometric formulas. Given: sin A - B = 1 10 and cos A + B = 2 29. We know that, sin θ = 1 - cos 2 θ. We know that, cos θ = 1 - sin 2 θ. Step 2: Find the value of the tangent of the sum and the difference of A and B. Since, cos A + B = 2 29 and sin A + B = 5 29. Since, sin A - B = 1 10 and cos A - B = 3 10. WebThe expansion of sin(a - b) formula can be proved geometrically. To give the stepwise derivation of the formula for the sine trigonometric function of the difference of two angles geometrically, let us initially assume that 'a', 'b', and (a - b) are positive acute angles, such that (a > b).In general, sin(a - b) formula is true for any positive or negative value of a …
