Therefore, the sine of an angle cannot be 35. OTHER SETS BY THIS CREATOR. Some examples will suffice to explain the approach. From the definition of sine and the fact that the area of a triangle is half the product of the altitude and the base, it follows that the are of a triangle is half the product of any of the two side times sin of the included angle. In order to use inverse trigonometric functions, we need to understand that an inverse trigonometric function “undoes” what the original trigonometric function “does,” as is the case with any other function and its inverse. 1) Find AC 15 yd C B A 28° 92° 2) Find BC 10 yd C B A 15° 59° 3) Find AC 25 m C B A 83. • Additional Properties: — y =sinx is an odd function, that is sin(−x)=−sinx 1. 5) equals 0. To graph the tangent function, we mark the angle along the horizontal x axis, and for each angle, we put the tangent of that angle on the vertical y-axis. The function called “arctan” or tan −1 reverses the tan function, and returns the original angle when you apply it to the tan of the angle. Definition of sine, cosine, tangent, cotangent, secant, and cosecant. So, we’re going to review sine, cosine, and tangent.
