How do you find the cosine and tangent of an angle if you are given the
sine? You may make up (if you like) an example of this to help
illustrate (remember, sine can only be between -1 and 1).
We have the sin²x+cos²x=1, so we can find the cosine if we have the sine,after we have sin,cos, easily to find the tangent by usingtangent =Sine/cosine
