How to solve for sine cosine and tangent
WebCosine $\theta$ = adjacent/hypotenuse; Tangent $\theta$ = opposite/adjacent; In order to calculate the sine or the cosine or the tangent I need to know $3$ sides of a right triangle. $2$ for each corresponding trigonometric function. How does a calculator calculate the sine, cosine, tangent of a number (that is actually an angle ?) without ... WebA sine of an angle, a cosine of an angle, and a tangent of an angle represent ratios of sides of a right triangle. If we’re given an angle of one side, we can use one of these trigonometric functions to find the other sides. For example: I’ll review what side is the opposite and the hypotenuse later. One way to memorize this is memorize:
