sin(x)= 1 csc(x) cos(x)= 1 sec(x) tan(x)= 1 cot(x) Warning: The reciprocal of sin(x) is csc(x), not sec(x). Note: We typically treat “0” and “undefined” as reciprocals when we are dealing with basic trigonometric functions. Your algebra teacher will not want to hear this, though! Quotient Identities tan(x)= sin(x) cos(x) and cot(x)= cos(x) sin(x)

derivatan är väl då ((cos x dx sin x) -(cos x sin x dx))/(sin x)^2 Edit: Räknade på secx=tanx=sinx/cosx och fick att dx secx=1/cos^2x. upg

tan ^2 (x) + 1 = sec ^2 (x) . cot ^2 (x) + 1 = csc ^2 (x) . sin(x y) = sin x cos y cos x sin y sin 2 ( x ) + cos 2 ( x ) = 1 1 + tan 2 ( x ) = sec 2 ( x ) 1 + cot 2 ( x ) = csc 2 ( x ) Domain of sin x and cos x In any right angle triangle, we can define the following six trigonometric ratios. sin x, cos x, csc x, sec x, tan x, cot x In the above six trigonometric ratios, the first two trigonometric ratios sin x and cos x are defined for all real values of x. Favorite Answer sec (x) = 1/ [sin (pi/2 - x)] = 1/cos (x) = tan (x)/sin (x) sin 2 (x) + cos 2 (x) = 1. tan 2 (x) + 1 = sec 2 (x). cot 2 (x) + 1 = csc 2 (x).

\mathrm {cosec} x=\dfrac {1} {\sin x} cosecx = sinx1. $$0=\sin2x\sec x+2\cos x=2(\sin x+\cos x)\implies \sin x+\cos x=0$$ and now observe that when $\;\cos x=0\;$ we do not get a solution as sine and cosine do not vanish on the same points, thus for the solution(s) of the equation we can assume $\;\cos x eq0\;$ , and then dividing by it $\begingroup$. . . . . the following: $(\cos x/(1-\sin x))-\tan x$ $=(\cos x/(1-\sin x))-(\sin x/\cos x)$ $=(\cos^2 x-\sin x(1-\sin x))/((1-\sin x)\cos x)$ $=(\cos^2 x - \sin x + \sin^2x)/((1-\sin x)\cos x)$, and so on, going down the left column above until you get to $1/\cos x$, then go on: $=\sec x$, and if necessary (but it's not necessary in this case) continue with a string of equalities Range of f(x) = sin-1 x + tan-1 x + sec-1 x is (A) ((π/4), (3π /4)) (B) [(π/4), (3π /4)] (C) (π/4), (3π /4) (D) None of these.
