A general equation for the sine function is y = A sin Bx. The A and B are numbers that affect the amplitude and period of the basic sine function, respectively. What does cos sin and Tan mean? Sin stands for sine, cos stands for cosine, and tan stands for tangent. They are used in trigonometry to find the lengths of sides. Sum, difference, and double angle formulas for tangent. The half angle formulas. The ones for sine and cosine take the positive or negative square root depending on the quadrant of the angle θ/2. For example, if θ/2 is an acute angle, then the positive root would be used. Truly obscure identities. These are just here for perversity. A: The basic trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These functions relate the ratios of the sides of a right-angled triangle to the angles in the triangle. Q: What is the formula for sin? Billy Tangent naively thought that the hyperbolic cosine function and the standard cosine function were the same. To make sure, he tried one real value and, sure enough, he got the same result. What value did he try? If you think there are multiple values for which this would work, enter 99999 as your answer. .
