WebHint: write f(x) = \dfrac{\ldots}{\cos(2x)} and simplify the numerator. Then look at the intervals between points where the numerator or denominator is 0. WebSep 5, 2024 · Use the identity \(\sin (\theta+2 \pi)=\sin \theta\) to simplify \(\sin \left(4 \pi+\frac{\pi}{6}\right)\). The correct answer is \(\frac{1}{2}\). The Graph of the Cosine Function. Now our goal is to graph \(y = \cos \theta\). We will go through the same procedure as we did for the sine function, and the result will be similar. WebMar 29, 2014 · 7 years ago. You have to know that sin (30 degrees) = sin (pi/6) is 1/2. This is the only trig function you have to memorize. Then, from the Pythagorean theorem, cos (30) is rt (3)/2. You can figure out sin (45) (see this video). From these you can get all the 12 simplest angles on the unit circle (8 multiples of 30 deg, 4 multiples of 45 (plus ... iosh accredited training
