What is the value of cosine {eq}134^\circ 19' {/eq}?Evaluating Trigonometric Function of a Non-special AngleIn an instance that the trigonometric expression is incorporated with a non-special angle, we can use the derived trigonometric table in which certain trigonometric functions have a value...
The unit circle can be used to define the trigonometric ratios, sine, and cosine. The sine refers to the ratio of the opposite side of a triangle to the hypotenuse while the cosine is the ratio of the adjacent side to the hypotenuse. Since the unit circle has a radius of one, the ...

P is a variable point on the curve y= f(x) and A is a fixed point in the plane not lying on the curve. If PA2 is minimum, then the angle between PA and the tangent at P is View Solution Cosine of the acute angle between the curve y=3x−1logex and y=xx−1, at the ...
What is the arccos of 0 ? arccos 0 = ? The arccosine is the inverse cosine function. Since cos 0 = cos 0º = 1 The arccosine of 0 is equal to the inverse cosine function of 0, which is equal to π/2 radians or 90 degrees: arccos 0 = cos-1 0 = π/2 rad = 90º See...
