You can also get the "Reciprocal Identities", by going "through the 1"Here you can see that sin(x) = 1 / csc(x)Here is the full set:sin(x) = 1 / csc(x) cos(x) = 1 / sec(x) cot(x) = 1 / tan(x) csc(x) = 1 / sin(x) sec(x) = 1 / cos(x) tan(x) = 1 ...
1. Trigonometric Identities You need to multiply top and bottom by 1−sinx1−sinx. Why? Because (experience tells me) it will help us get it in the right form.Re: Prove the trig identity cosx/(secx+tanx)= 1-sinx Alexandra 01 Jan 2016, 20:13 cos2x(1−sinx)...
Trig identities are notoriously difficult to memorize: here’s how to learn them without losing your mind. Starting from the Pythagorean Theorem and similar triangles, we can find connections between sin, cos, tan and friends (read the article on trig). Can we go deeper? Maybe we can ...
