Sin cos tan values are the primary functions in trigonometry. Learn the values for all the angles, along with formulas and table. Also, learn to find the values for these trigonometric ratios.
Use the identities tan(x) = sin(x)/cos(x) and csc(x) = 1/sin(x) to get: 1/(tan(x) × csc(x)) = 1/[(sin(x)/cos(x) × 1/sin(x)] Now just work with the denominator (bottom) of the rational expression (fraction): sin(x)/cos(x) × 1/sin(x) = 1/cos(x) Now ...
cos(u)sec(u)tan(u)=cot(u) Proving Trigonometric Identities: To prove true, given trigonometric identities, we must use the trigonometric identities already established in a right triangle, such as sec(x)=1cos(x), tan(x)=sin(x)cos(x), cot(x)=...
{eq}\displaystyle \sin \theta \tan \theta + \cos \theta = \sec \theta {/eq}. Trigonometric Identities: Trigonometric identities are equality functions that are true for any value of the unknown angle quantity. For example, {eq}\cos 2x = 2\cos x - 1 {/eq} is a ...
