WebOct 26, 2024 · Students were asked to prove the identity (sec x)(csc x) = cot x + tan x. Two students' work is given.Student AStep 1: 1 over cosine x times 1 over sine x equals cotangent x plus tangent xStep 2: 1 over cosine x times sine x equals cotangent x plus tangent xStep 3: cosine squared x plus sine squared x over cosine x times sine x equals … Webtan(x y) = (tan x tan y) / (1 tan x tan y) . sin(2x) = 2 sin x cos x cos(2x) = cos ^2 (x) - sin ^2 (x) = 2 cos ^2 (x) - 1 = 1 - 2 sin ^2 (x) . tan(2x) = 2 tan(x) / (1 ...

WebAnd so zero times cosine of x, that is just zero. And so all we are left with is sine of x over cosine of x squared. And there's multiple ways that you could rewrite this if you like. You could say that this is same thing as sine of x over cosine of x times one over cosine of x. And of course this is tangent of x, times secant of x. Secant of x. WebMar 10, 2015 · From math class, some trigonometric identities: cot x = 1/tan x csc x = 1/sin x sec x = 1/cos x There are no built-in cot or csc formulas, so use the above. Remember that these... WebThe derivative of sec x is sec x times tan x (i.e., "the other one"). See also definition of the secant (sec) trigonometric function. 5. Derivative of cot(x) ...
