WebLearn about the relationship between the sine & cosine of complementary angles, which are angles who together sum up to 90°. We want to prove that the sine of an angle equals the cosine of its complement. \sin (\theta) = \cos (90^\circ-\theta) sin(θ) = cos(90∘ − θ) [I'm skeptical.

The two kinds of "inverse" trigonometric functions can feel a bit esoteric when you're new to them, but let's pretend cos x = 7 x + 12. Then arccos x = x − 12 7 while sec x = 1 7 x + 12, which is clearly completely different. Share.

Web22 aug. 2015 · If you use this and Pythagoras' Theorem, you should be able to get the answer. Remember that cos θ is just the -coordinate of a point at angle θ on the unit circle. Knowing that cos θ = − 4 5 and that θ is in the third quadrant, you should be able to make a rough sketch of that point. Websec (θ) = 1/cos (θ) cot (θ) = 1/tan (θ) And we also have: cot (θ) = cos (θ)/sin (θ) Pythagoras Theorem For the next trigonometric identities we start with Pythagoras' Theorem: Dividing through by c2 gives a2 c2 + b2 c2 = c2 c2 This can be simplified to: ( a c )2 + ( b c )2 = 1 Now, a/c is Opposite / Hypotenuse, which is sin (θ)
