WebPurplemath. In mathematics, an "identity" is an equation which is always true. These can be "trivially" true, like " x = x " or usefully true, such as the Pythagorean Theorem's " a2 + b2 = c2 " for right triangles.

WebTan2 x = sin2 x divided by cos2 x cot2 x = cos2 x divided by sin2x add those together you ge ( sin2 x times sin2 x ) / ( cos2 x times sin2 x ) + ( cos2 x times cos2 x ) / ( sin2x times cos2 x) they both have same denominator ( order doesn’t matter for multiplication ) so you have (sin4 x + cos4 x )/ (cos2 x times sin2 x) which does not equal 2. WebFor cos 450°, the angle 450° > 360°. Given the periodic property of the cosine function, we can represent it as cos (450° mod 360°) = cos (90°). The angle 450°, coterminal to angle 90°, lies on the positive y-axis. Thus cos 450 degrees value = 0. Similarly, cos 450° can also be written as, cos 450 degrees = (450° + n × 360°), n ∈ Z.
