sin(x) = sqrt(1-cos(x)^2) = tan(x)/sqrt(1+tan(x)^2) = 1/sqrt(1+cot(x)^2) cos(x) = sqrt(1- sin(x)^2) = 1/sqrt(1+tan(x)^2) = cot(x)/sqrt(1+cot(x)^2) tan(x) = sin(x cos(267°) + cos(273°) = 0 cos(268°) + cos(272°) = 0 cos(269°) + cos(271°) = 0 So all those cosines in the sum cancel out. Thus the only cosines in that sum that we haven't considered are cos(90°) = 0, cos(180°) = -1, and cos(270°) = 0 And their sum is -1. So that's the answer, -1. Edwin prove sec (x) - tan (x)sin (x) =cos (x) and cot^2 (x) (1-cos^2 (x)) = cos^2 (x) 3:01.

The notation with the "arc" prefix avoids such a confusion, though "arcsec" for arcsecant can be confused with "arcsecond". In any triangle we have: 1 - The sine law sin A / a = sin B / b = sin C / c 2 - The cosine laws a 2 = b 2 + c 2 - 2 b c cos A b 2 = a 2 + c 2 - 2 a c cos B c 2 = a 2 + b 2 - 2 a b cos C Relations Between Trigonometric Functions Weekly Subscription $1.99 USD per week until cancelled Monthly Subscription $6.99 USD per month until cancelled Annual Subscription $29.99 USD per year until cancelled Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history To do this we use the Pythagorean identity sin 2 (A) + cos 2 (A) = 1. In this case, we find: cos 2 (A) = 1 − sin 2 (A) = 1 − (3/5) 2 = 1 − (9/25) = 16/25. The cosine itself will be plus or minus the square root of 16/25.

It is indeed true that \sin^{2}(x)=1-\cos^{2}(x) and that \sin^{2}(x)=\frac{1-\cos(2x)}{2}. Notice that cos 2 ( x ) : = ( cos ( x ) ) 2 is not the same thing as cos ( 2 x ) .

The notations sin −1, cos −1, etc. are often used for arcsin and arccos, etc. When this notation is used, inverse functions could be confused with multiplicative inverses. The notation with the "arc" prefix avoids such a confusion, though "arcsec" for arcsecant can be confused with "arcsecond". cos − 1 (x y − 1 − x 2 1 − y 2 ) = π − cos − 1 z x y − 1 − x 2 1 − y 2 = cos ( π − cos − 1 z ) x y − 1 − x 2 1 − y 2 = − cos ( cos − 1 z ) prove sec (x) - tan (x)sin (x) =cos (x) and cot^2 (x) (1-cos^2 (x)) = cos^2 (x) 3:01.
