WebApr 27, 2024 · In trigonometry, Tan2x is a double angle identity. Because the tangent function is a ratio of the sine and cosine functions, it may also be represented as tan2x = sin 2x/cos 2x. It’s an important trigonometric identity that’s utilized to solve a wide range of trigonometric and integration problems. WebOct 1, 2016 · How do you prove 1 + tan2(x) = sec2(x)? Trigonometry Trigonometric Identities and Equations Proving Identities 1 Answer George C. Oct 1, 2016 See explanation... Explanation: Starting from: cos2(x) + sin2(x) = 1 Divide both sides by cos2(x) to get: cos2(x) cos2(x) + sin2(x) cos2(x) = 1 cos2(x) which simplifies to: 1 + tan2(x) = sec2(x) Answer link

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.
