From SOH CAH TOA, we get sin(30°)= = cos(60°) and cos(30°) = = sin(60°) The table now looks like. θ sin(θ) cos(θ) 0° 30° 45° 60° 90° and we note that because of the property of complementary angles discussed earlier, every time we determine 2 trig values, we effectively get 2 more free of charge.

Given a value of sin Ө, cos Ө or tan Ө, we can find the value of the angle Ө using the sin-1, cos-1 or tan-1 keys, respectively. On most calculators, sin-1, cos-1 and tan-1 is obtained by first pressing . INV. or . 2nd F. and then pressing sin, cos or tan, respectively. Example. Find the value of Ө, to the nearest minute, given that: (i ...

to each of the following angles, and use the side lengths and a calculator to find the cosine of each angle. Use the Gizmo to check. cos 15° = cos 30° = cos 45° = cos 60° = Compare cos 35° and sin 55°. In general, how does cos(θ) relate to sin(90 – θ)?

Sin θ/cos θ = tan θ not for 90° & 270° or multiples. Cos θ/sin θ = cot θ not for 0°, 180° & 360° or multiples Reciprocal Identities (Important in Calculus) These come from the definitions and they are just the pairings that relate to being the reciprocal of the given trig f(n) – sin θ, cos θ or tan θ.
