Cos(x) equals zero at 90 degrees and 270 degrees. If x exceeds 360 degrees, cos(x) will equal zero at any increment of 90 + 180(n) degrees. In radians, this is equivalent to (pi/2) + pi(n) radians.
cos 315 degrees is 4th quadrant same as cos (-45) degrees which is +0.7071
cos 34o ≈ 0.829 cos 34 = 0.86074
cos(25o) = 0.906307787 ==========
cos(495) = cos(495-360) = cos(135) = -cos(180-135) = -cos(45) = -sqrt(1/2) or -1/sqrt(2)
47 degrees Celsius is equal to a temperature of 116.6 degrees Fahrenheit.
cos(125) = cos(180 - 55) = cos(180)*cos(55) + sin(180)*sin(55) = -cos(55) since cos(180) = -1, and sin(180) = 0 So A = 55 degrees.
The inverse cos of 1 is equal to o degrees. You can find this answer by knowing what angle measurement has cos equal to a value of 1.
cos(42o) = 0.7431448255 ==============( approximately 37/50 )
cos-1(0.74) = 42.26858443 degrees
(-1-√3)/(2√2)
-47 degrees Celsius is equal to -52.6 degrees Fahrenheit.
Cos(x) equals zero at 90 degrees and 270 degrees. If x exceeds 360 degrees, cos(x) will equal zero at any increment of 90 + 180(n) degrees. In radians, this is equivalent to (pi/2) + pi(n) radians.
47 degrees Fahrenheit is approximately 8.33 degrees Celsius.

When x = 75.964 degrees plus or minus any multiple of 180 degrees.
47 degrees Celsius = 116.6 degrees FahrenheitUse this equation to convert degrees Celsius/Centigrade (ºC) to degrees Fahrenheit (ºF): (ºC x 1.8) + 32 =ºF
