Web19 jul. 2013 · Using A.M ≥ G.M logic for tan 2 θ + cot 2 θ we get , = 1 + 2 + sec 2 θ + cosec 2 θ. changing into sin and cos values. ( Because we know maximum and minimum values of Sin θ, Cos θ :P and by using simple identities we can convert all trigonometric functions into equation with Sine and Cosine.) Websin θ = y 1. Start measuring the angles from the first quadrant and end up with 90° when it reaches the positive y-axis. Now the value of y becomes 1 since it touches the circumference of the circle. Therefore the value of y becomes 1. sin θ = y 1 = 1 1. Therefore, sin 90 degree equals to the fractional value of 1/ 1. tallahassee hotels near meWebH = Sin ( 30 degrees ) * L The Sin of 30 degrees is 0.5.
