WebbWhat is the formula of Sin 3 x? Solution: We can find the value by using the trigonometric identity of sin 3 x As per trigonometric identity, we have sin 3x = 3sin x - 4sin 3 x On transposing terms, 4 sin 3 x = 3sinx - sin 3x Divide both sides of the equation 4 sin 3 x = 3sinx - sin 3x by 4, sin 3 x = (3sinx - sin 3x)/4 WebbSimplify trigonometric expressions Calculator online with solution and steps.
