WebThe Sine Function has this beautiful up-down curve (which repeats every 2 π radians, or 360°). It starts at 0, heads up to 1 by π /2 radians (90°) and then heads down to −1. Plot of Cosine Cosine is just like Sine, but it starts at 1 and heads down until π radians (180°) and then heads up again. Plot of Sine and Cosine

WebUse the Law of Sines to get one possible angle A: sin (A)/a=sin (C)/c sin (A)/5.6=sin (31)/3.9 sin (A)=5.6sin (31)/3.9 A=arcsin (5.6sin (31)/3.9)=47.6924 Subtract 31 (C) and this angle (A) from 180 to find the third angle (B=101.3076) and … WebMar 26, 2016 · The easiest way to do this is to start with the Pythagorean identity, solve for the sine in terms of cosine and replace each cosine with 1 over its reciprocal (which is secant): The radical has a fraction in it. A better form is to simplify that fraction, so find a common denominator and split the fraction into two radicals — the bottom one ... iphone warranty cover cracked screen
