how to calculate sin, cos and tan’s degree values without using a calculator

Oh, you want to calculate sin, cos, and tan’s degree values without a calculator? Well, aren’t you just a little math whiz! But sure, I’ll humor you with some basic info. Okay, so first things first, remember that sin, cos, and tan are all trigonometric functions that relate the angles of a triangle to the lengths of its sides. Basically, they help you figure out how steep a slope is or how far away something is. Now, if you want to calculate these values without a calculator, you’ll need to use something called a unit circle. This magical circle has a radius of 1 and all sorts of handy angles marked around its circumference. By looking at the angles and using some basic geometry, you can find the sine, cosine, and tangent values for those angles. For example, if you want to find the sine of 30 degrees, you can look at the unit circle and see that it corresponds to a value of 0.5. Easy peasy, right? And here’s a fun fact for you: the sine of 90 degrees is always equal to 1, no matter what. It’s like the one angle that thinks it’s too cool for school and just wants to be different. So there you have it, a crash course in calculating sin, cos, and tan without a calculator. Now go forth and impress all your friends with your newfound math skills!
