WebbWe 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 … WebbNow apply the power-reduction formula for cosine on the last term in the parentheses: Factor out 1/2: or. We see that all trigonometric terms appear to the first power only, so …
Webbsin3x = 3sinx − 4sin3x cos3x = 4cos3x − 3cosx I expect you are familiar with these formula. Actually most of these can be derived from the first one itself. Share Cite Follow … Webbsin 5x = 5 cos 4 x sin x - 10 cos 2 x sin 3 x + sin 5 x (1) Using the identity, sin 2 x + cos 2 x = 1 rearranged as cos 2 x = 1 - sin 2 x, we can say cos 4 x = (1 - sin 2 x) 2 = 1 - 2 sin 2 x + sin 4 x , substituting this into (1) expanding and collecting terms we get the final answer: sin 5x = 16 sin 5 x - 20 sin 3 x + 5 sin x Answered by Tom R.

WebbInverse hyperbolic functions. If x = sinh y, then y = sinh-1 a is called the inverse hyperbolic sine of x. Similarly we define the other inverse hyperbolic functions. The inverse hyperbolic functions are multiple-valued and as in the case of inverse trigonometric functions we restrict ourselves to principal values for which they can be considered as single-valued.
