In this example problem, we use the phrase "all students take calculus" to help identify in which quadrant an angle will be located based on trigonometric trig functions being positive or negative at the given angle. sine, cosine, tangent, secant, and cosecant functions are used in examples. Each part of this process is explained and written out step-by-step.
