1. Problem: If the sine of theta is (3/8) and theta is in the first quadrant, what is sin 2(theta). (Use the figure below.) ... Solution: From the diagram, we see that cos (theta) = (SQRT(55)/8. Use the double angle identity for sine. sin 2(theta) = 2(sin (theta))(cos (theta)) Plug in the values you ... Back to Trigonometry...

Well it is nearly one in the morning and I have tons of work to do and a fabulous idea pops into my head: How about writing an introductory tutorial to trigonometry! I am going to ... Now with that picture we can think of sine, cosine and tangent in a different way: sin (theta) = x/r cos (theta)= y/r tan (theta)= y/x --

The sine function, is one of the three main trigonometry functions. The sine of the angle theta is the ratio of the opposite side over the hypotenuse. This ratio is the same on any size circle.
