The right triangle formulas are the most important ones in the trigonometry. The sin Theta is the ratio of the opposite side to the hypotenuse, If theta Θ is one of the acute angles. Sin x Formula: It is one of the formulae of the Sin function from the six other trigonometric functions.

how can i solve this if the only given is sin theta= -3 tan theta= cos theta= cot theta= co secant theta= secant theta= can you teach me and show how to solve?? Hi Jonathan. That question has no answer. Look at a sine wave: all the values of fx = sinx vary between -1 and 1,. Trigonometry is a branch of mathematics. It deals with right triangles. A right triangle has one right angle and two acute angles. Letting one acute angle be θ and the other acute angle be 90°- θ. Obviously, right triangles have three sides edg. We're given that sintheta = 1/3, which means that the side opposite theta measures 1 unit and the hypotenuse measures 3. However, we don't know the measure of the side adjacent. Since we're working with right triangles, we can use pythagorean theorem to determine the missing side. 22/04/2009 · tan x = sinx /cosx. so. 2tan theta = 3sin theta. 2sintheta/cos theta = 3sin theta, simplify sin theta. 2/costheta = 3. so. 3cos theta = 2. cos theta = 2/3. theta = arccos 2/3. 08/08/2010 · My maths teacher taught us this cool rhyme to help us with this: Shield Your Rear, Cause X-Rays Tan Your Exterior.sin= y/r, cos= x/r and tan=y/x Ok so lets say that sin theta.

General Value: nπ tan-13/5 Principal Value: tan-13/5. Free math lessons and math homework help from basic math to algebra, geometry and beyond. Students, teachers, parents, and everyone can find solutions to their math problems instantly.

Please see the proof below We need sin2theta=2sinthetacostheta cos^2thetasin^2theta=1 cos2theta=1-2sin^2theta First calculate sin3theta sin3theta=sin2thetatheta =sin2thetacosthetacos2thetasintheta =2sinthetacos^2theta1-2sin^2thetasintheta =2sintheta1-sin^2theta1-2sin^2thetasintheta =3sintheta-4sin^3theta And 12cos2theta=121-2sin.
