The easiest way to find the value of sin(20) is to use a scientific calculator or a computer.
But if you want to actually calculate it, you could try the following. First you need to make sure that the angle is expressed in radians. 180 degrees = pi radians so 20 degrees =20*pi/180 = pi/9 radians. Call this value x.
Then find x/1! - x3/3! + x5/5! - x7/7! + ...
The further you go, the more accurate your result.
The calculators have been programmed in such a way that they are able to calculate sin, cos and tan without the side lengths.
20% of 24.94= 20% * 24.94= 0.20 * 24.94= 4.988

sin-1(1/20) = 3 degrees.
To calculate win-lose, add the wins and the losses and divide the sum into the wins to calculate percentage of wins or divide into the losses to calculate the percentage of losses: W + L = Total; W ÷ Total = W%; L ÷ Total = L%: example: 12 W + 8 L = 20; 12W ÷ 20 = .60 or 60% wins; 8L ÷ 20 = .40 or 40% losses
To find the angle of incidence when the angle of refraction is 20 degrees, you can use the formula for Snell's Law: n1 sin(θ1) = n2 sin(θ2). Given that n1 and n2 are the refractive indices of the media and we know θ2 (20 degrees), you can calculate θ1.
Like normal expansion of brackets, along with: cos(A + B) = cos A cos B - sin A sin B sin(A + B) = sin A cos B + cos A sin B 5(cos 20 + i sin 20) × 8(cos 15 + i sin 15) = 5×8 × (cos 20 + i sin 20)(cos 15 + i sin 15) = 40(cos 20 cos 15 + i sin 15 cos 20 + i cos 15 sin 20 + i² sin 20 sin 15) = 40(cos 20 cos 15 - sin 20 cos 15 + i(sin 15 cos 20 + cos 15 sin 20)) = 40(cos(20 +15) + i sin(15 + 20)) = 40(cos 35 + i sin 35)
i think sin 200 is smaller than sin 0.. because sin 200= - sin 20.. sin 0 = 0 of course 0 > - sin 20

type the value of sine in the calculator and press 2ND SIN for sin-1, or press 2ND SIN for sin-1 and type the value of sine, because -sin(.xxxx) = angle known as inverse sine
sin (theta) = [13* sin (32o)]/8 = 13*0.529919264/8 = 0.861118804 [theta] = sin-1 (0.861118804) [theta] = 59.44o
You can use the L'hopital's rule to calculate the limit of e5x -1 divided by sin x as x approaches 0.
cos(phi - 1) = cos(phi)cos(1) + sin(phi)sin(1)
