sin 15 without calculator, you can construct a 30-60-90 degree special right triangle, which contains an angle of 30 degrees and another of 60 degrees. The hypotenuse is always twice the length of the shorter side. For a hypotenuse of 2, the shorter side is 1. Sin 30 = Opposite/Hypote...
eq1 = Pa-N*sin(theta)+T*cos(theta) == 0; eq2 = Q+W-Pa*tan(delta)-N*cos(theta)-T*sin(theta) == 0; eq3 = T == c*L + N*tan(phi); % Solution sol = solve([eq1,eq2,eq3], [N, T, Pa], 'returnconditions', true); Pa_theta = symf...
(25)/7. Rearranging this equation results in sin(A) = sin(25)*12/7. Using a scientific calculator to find sin(25), carrying out the rest of the equation would show that sin(A) = 0.724. To find angle “A,” use the calculator to determine the inverse sine of 0.724. The answer ...
