WebWhat is the value of sin(2x) if cos(x) = 2/5 and x is between 270 and 360 degrees? Find the value of sin(2x) if cos(x) = 2/5 and x is between 270 and 360 degrees. WebExpress cos 2 x in terms of tan x. Solution Step 1 : Apply the identity of cos 2 θ As we know the identity cos 2 θ = cos 2 θ - sin 2 ( θ) so, substituting θ = x, cos ( 2 x) = cos 2 ( x) - sin 2 ( x) Now, cos ( 2 x) = cos 2 ( x) - sin 2 ( x) 1 cos ( 2 x) = cos 2 ( x) - sin 2 ( x) cos 2 ( x) + sin 2 ( x) cos 2 ( x) - sin 2 ( x) = 1

WebInverse 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.
