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.

How do you calculate win- lose?
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
How do you calculate sin20?
You need to use a calculator or computer. The answer will depend on whether the angle is measured in degrees or radians.
When the angle of refraction is 20 degrees what is the angle of incidence?
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)
Which is smaller sin 0 or sin 200?
i think sin 200 is smaller than sin 0.. because sin 200= - sin 20.. sin 0 = 0 of course 0 > - sin 20
