Its basically a picture of certain common values for sine and cosine for angles such as π 6 or 2π 3. sqrt3/2 There are 2 ways, that don't need calculator a. Trig table of special arc --> cos (pi/6) = sqrt3/2 b. Use triangle trigonometry Consider a right triangle ABH that is half of an equilateral triangle ABC Angle A = pi/6 = 30^@, Angle B TheU is equal to sin of X. We have our sin of X here for the first part of the integral, for the first integral. We have the sin of X and then this is going to be minus. Let me just write it this way. Minus 1/3 minus 1/3. Instead of U to the third, we know U is sin of X. Sin of X to the third power. TrigonometryExamples. Rewrite csc(x) csc ( x) in terms of sines and cosines. Combine cos(x) cos ( x) and 1 sin(x) 1 sin ( x). Convert from cos(x) sin(x) cos ( x) sin ( x) to cot(x) cot ( x). Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just sin^2(x/2) = (1-cos(x))/2# #color(blue)(sin(x/2) = pmsqrt((1-cos(x))/2))# We can see that if we take the conditions for positive and negative values from #sinx# and #cosx# and divide them, we get that this is positive for quadrants I and III and negative for II and IV.
