tan(405) = tan(360 + 45)
tan(360 + 45) = (tan(360) + tan(45))/(1 - (tan(360) * tan(45)))
tan(360 + 45) = (0 + 1)/(1 - 0)
tan(360 + 45) = 1/1
tan(405) = 1

tan of 405 would be the same thing as 45 degrees because
405-360=45
(it wraps around the unit circle)
tan of 45 happens to be 1

tan 405 degrees = tan 45 degrees = 1, because the
tangent repeats itself every 180 degrees.

405 degrees =360 degrees +45 degrees.
All we need is the tangent of 45, which is 1.0000000000....

sin(-240) = sin(one hundred twenty). on the unit circle, it somewhat is sqrt(3)/2 cos (-510) = sin (-a hundred and fifty) = sin (210). on the unit circle the respond is -a million/2 tan (13pi/3) = tan (pi/3). Tan is sin/cos, or sqrt(3)/2 / a million/2. Multiply by potential of the reciprocal it somewhat is sqrt(3)/2 * 2/a million, it somewhat is the sqrt(3).

Same as the tangent of 40 degrees
