Sin a + sin b

It is one of the sum to product formulas used to represent the sum of sine function for angles A and B into their product form. From this, sin a + sin b. We will solve the value of the given expression by 2 methods, using the formula and by directly applying the values, and compare the results.

The sum of two sines is equal to the cosine of their difference multiplied by the product of their amplitudes. The two sines are out of phase with each other if their difference is not an integer multiple of pi. In trigonometry, the sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse. The cosine of an angle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse. The tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side.
