Find the angle theta between u = < 0, 1, 1 > and w = < 1, 1, 0 >. Give theta in radians. Suppose sin (theta) =1/5. Find the exact value of csc (theta). If theta = pi/2, determine the exact value of sin theta. ...
We know that the exact value of cos 0 degrees is 1 So, cos 180 degree is -(cos 0) which is equal to -(1) Therefore, thevalue of cos 180 degrees = -1 It is also represented in terms of radians. So,value of cos pi = -1 ...
