WebDec 7, 2015 · It's the same number. Start from the point (1,0) on the unit circle, which is when we have an angle of 0 radians. From there, try to move along the circumference, running the same angle, a first time counterclockwise, and a second time clockwise. These two angles are theta and -theta. As you can see, you'll end up with two points which lie … WebŘešte matematické úlohy pomocí naší bezplatné aplikace s podrobnými řešeními.

Webcot θ = cos θ sin θ The proof is here. Example 1. Show: tan θ cos θ = sin θ. Solution: The problem means that we are to write the left-hand side, and then show, through substitutions and algebra, that we can transform it to look like the right hand side. We begin: We have arrived at the right-hand side. Pythagorean identities
