1 Any number over itself equals to one
Can you please claify if you mean x=y^2/ pi*cos(x) , or x=y^2/cos(pi), since they are very different sums.
sin(pi/2)=1
The answer is:cos (pi/2) = 0
Cos(Pi/3) is 1/2 so Cos(-Pi/3) ould be flipped over the x-axis. The answer is still 1/2.
45 degrees are pi/4 radians. You can verify this with a unit circle.
180/pi, just over 57 degrees.
if 360 degrees is equal to 2 Pi (3.14...) so 180 degrees is equal to 1 PI or just Pi
45 degrees (+/- 180k degrees for any integer k) or pi/4 radians (+/- pi*k radians for any integer k).
pi over three is 60 degrees.
It is pi/4 radians.
A radian is 180/pi degrees, or about 57 degrees
180
180
No, 360 degrees is equal to 2 pi radians, or about 6.28 radians.
A radian is a degree of measure where an entire circle is set equal to 2 x pi. If you use degrees, the circle is equal to 360 degrees. Therefore, each radian is equal to 180 / pi degrees, or about 57.30 degrees. Since milli means thousandths, a milliradian is about 0.05730 degrees.
Pi is the ratio of a circle's circumference to its diameter, about 3.14159. Pi radians is equal to 180 degrees.
