How do you find theta? - Socratic
2016年9月18日 · Whichever ratio you are most comfortable with. For example: theta=arcsin(b/c) and theta=arccos(a/c) You can use any of the six standard trigonometric functions to find theta. I'll show you how to find it in terms of arcsine and arccosine. Recall that the sine of an angle theta, denoted "sintheta", is the side opposite of theta divided by the hypotenuse of the triangle. In …
What is 'theeta' angle in trigonometry? - Socratic
2018年5月28日 · See below: Simply put, theta (theta), is a Greek letter utilized extensively throughout trig to denote an angle. When you see sintheta, this just means the sine of an angle, where theta is the angle Hope this helps!
What is polar cis form? - Socratic
2015年6月17日 · Polar cis form is the polar form of a complex number: r(cos theta + i sin theta) often abbreviated as r cis theta A complex number z is always expressible uniquely as a+ib, where a, b in RR. That is it is expressible as a point (a, b) in RR xx RR. Any such point can also be represented using polar coordinates as (r cos theta, r sin theta) for some radius r >= 0 and …
What is theta equal to and why? - Socratic

Polar Coordinates - Trigonometry - Socratic
A polar coordinate system consists of a polar axis, or a "pole", and an angle, typically #theta#.In a polar coordinate system, you go a certain distance #r# horizontally from the origin on the polar axis, and then shift that #r# an angle #theta# counterclockwise from that axis.
