2 Answers Hammer Mar 27, 2018 #sin theta = 1/csc theta = 1 / (4/3) = 3/4# #cos^2 theta = 1 - sin^2 theta = 1 - 9 / 16 = 7 / 16# #cos theta = +- sqrt7 / 4#
where sin 2 θ {\displaystyle \sin ^{2}\theta } means (sin θ) 2 {\displaystyle (\sin \theta)^{2}} and cos 2 θ {\displaystyle \cos ^{2}\theta } means (cos θ) 2. You want to simplify an equation down so you can use one of the trig identities to simplify your answer even more. Sin= đối/ huyền. Here are the formulas for these six trig ratios: Given a triangle, you should be able to identify all 6 ratios for all the angles (except the right angle).

The remaining three functions can all be expressed as reciprocals of functions we have already defined. cot x = 1 = cos x. Recall that tan 30° = sin 30° / cos 30° = (1/2) / (√3/2) = 1/√3, as claimed. Formulas of the derivatives of trigonometric functions sin(x), cos(x), tan(x), cot(x), sec(x) and csc(x), in calculus, are presented along with several examples involving products, sums and quotients of trigonometric functions. Example: Find cos 90, tan 90, sin 630, sin 135, tan (-405), sin 210, tan (-30). Finally, you could save time on your proof by noticing on the fourth step that $$ \frac{1}{\cos x\sin x}=\frac{1}{\cos x}\frac{1}{\sin x}=\sec x \csc x $$
