Working with trigonometric relationships in degrees Trigonometric functions can have several solutions. Sine, cosine and tangent all have different positive or negative values depending on what ...

Calculate the angle QPR. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). In the triangle the ...

Why? Because trigonometry itself is built upon the very theorem it seeks to prove. Any attempt at using sine, cosine, or tangent to verify Pythagoras’ equation seemed destined to rely on the ...
