In fact, theta = atan(-√3) = -1.047 radians For converting from radians to DEG you use: 180* (-1.047)/pi = -60 deg Because it is a negative angle, we are located in the four quadrant. But we can convert it to a positive angle just adding 360 deg as follows: Equivalent angle...
Use the fundamental trigonometric identities to simplify the expression. There is more than one correct form for each answer. \tan^2 \theta\csc^2\theta- \tan^2\theta Simplify the expression by using a double-angle formula. (2 tan 22)/(1- tan^2 22) Write as an...
The trig ratios are the basis for the study of trigonometry, which literally means "the measuring of angles and sides of triangles" in Greek. Here are the three ratios from which all other identities are found. The reader should be familiar with these three ratios. $$\sin\theta=\frac{\te...

What is the law of exponents to solve exponential equations? If a^u = a^v, the u = v Is y = 3^x and y = (1/3)^x identical? No, the function would have to be written as y = (1/3)^x needs to be written as y = 3^-x What is required for an exponential function to ...

Theta's initial side was the x-axis. IF a circle were to pass through this point then the distance from the origin to the circle would be a radius. If you consider the x & y coordinates of the point as “legs” of a right triangle, then you have what is sometimes called ...
