WebbQ. Assertion : sin(A+B)+sin(A−B) cos(A+B)+cos(A−B) =tanA Reason: sin(A+B)+sin(A−B)=sinA and cos(A+B)+cos(A−B)=cosA. Q. Prove that: (i) sinA+sin3A cosA−cos3A =cotA. (ii) sin9A−sin7A cos7A−cos9A =cot8A. (iii) sinA−sinB cosA−cosB =tanA−B 2. (iv) sinA+sinB sinA−sinBtan(A+B 2)cotA+B 2.

Now, substitute the values A = 6x and B = 3x into the formula. 2 Sin6x Sin3x = cos (6x – 3x) – cos (6x + 3x) = cos3x – cos9x. Therefore the expression 2 sin6x sin3x in terms of the cosine function is written as cos3x – cos9x.

WebbAdding all four equations ⇒ - 4 ≤ sin A + sin B + sin C + sin D ≤ 4 For sin A + sin B + sin C + sin D to be equal to 4, sin A = sin B = sin C = sin D = 1 Step 2: Calculate the given expression. Since sin A = sin B = sin C = sin D = 1 ⇒ sin A × sin B × sin C × sin D = 1 4 = 1 Hence, value of sin A × sin B × sin C × sin D is 1. Suggest Corrections 0

WebbBy using the cosine addition formula, the cosine of both the sum and difference of two angles can be found with the two angles' sines and cosines. This video shows the formula for deriving the cosine of a sum of two angles. cos (A + B) = cosAcosB − sinAsinB. We will use the unit circle definitions for sine and cosine, the Pythagorean identity ...

Using the formulae to solve an equation Example Suppose we wish to solve the equation cos2x = sinx, for values of x in the interval −π ≤ x < π. We would like to try to write this equation so that it involves just one trigonometric function, in this case sinx.
