Find the exact value of the trigonometric expression when u and v are in Quadrant IV and sin u = -3/5 and cos v = 1/sqrt(2). sin(u + v) Find the exact value of the trigonometric expression when u and v are in Quadrant IV and...
In trigonometry, we have a bunch of summation identities that work to find the exact value of the trigonometric function containing the sum of two angles. The general identities are given by: sin(x+y)=sinxcosy+cosxsinysin(x−y)=sinxcosy−c...

The value of tan 90 degrees is undefined. The tangent of an angle is equal to the ratio of sine and cosine of the same angle. Learn how to derive the exact value of tan 90 at BYJU’S.
(decimal form). therefore, the exact value of cos 30 degrees is written as 0.8660 approx. √3/2 is the value of cos 30° which is a trigonometric ratio or trigonometric function of a particular angle. cos 30 another alternative form of cos 30° is pi/6 or π/6 or cos 33 (...
Challenge:What is the exact value for sine of 6 degrees? How about sine of 1 degree? Context:I received a delightful email from reader James Parent recently. He wrote: I have the exact answers for the sin of all integer angles. Has anyone done this before? I'm retired, and a Profess...
Using a bench press calculator is necessary to determine this number because it's difficult to accurately guess the exact weight, taking into account the fatigue you may experience from trying multiple 1RM. Such a method would also not be particularly safe. A safer and more reliable way is to...
