Tan, cot, sec, and csc, calculated from trig identities. Once you know the value of sine and cosine, you can use the following trigonometric identities to obtain the values of the other four functions: Tangent is the sine-to-cosine ratio tan(α) = sin(α)/cos(α) Cosecant is the re...
Trig identities are notoriously difficult to memorize: here’s how to learn them without losing your mind. Starting from the Pythagorean Theorem and similar triangles, we can find connections between sin, cos, tan and friends (read the article on trig). Can we go deeper? Maybe we can ...
Related to Hyperbolic trig identities:Hyperbolic trig functions hyperbolic function n. Any of a set of six functions related, for a real or complex variablex,to the hyperbola in a manner analogous to the relationship of the trigonometric functions to a circle, including: ...
By one of the trigonometric identities, sin2y + cos2y = 1. From this, sin y = √1-cos²y = √1-x².Substituting this in (1),dy/dx = -1/√1-x² (or)d (arccos x) / dx = 1/√1-x²Thus, the derivative of arccos x (or) cos-1x (or) inverse cos x is 1/√1...
