Any number over itself equals to one
Yes, pi/4 = 45 degrees.
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.
pi is equal to 3.141592653589793238462643383279502884197169399375105...., pi is actually a endless mathematical ratio. pi is sometimes approximated by 22 over 7.
pi^2
Yes, pi/4 = 45 degrees.
No, 22 over 7 is not equal to pi, but is instead an approximation of pi, as it only gives you 3 digits of pi, the rest (after 3.14) in 22/7 are wrong. Pi is 3.141926......... And goes on forever, meaning that a fraction such as 22/7 will never be fully equivalent to pi.
sin(pi/4) and cos(pi/4) are both the same. They both equal (√2)/2≈0.7071■
0.3183 (approx)
12/pi is equal to 12/pi, 12/3.14 (most common rounding of Pi) is about 3.822
pi is equal to 3.14
Pi is approximately equal to 3.141592652389793238462.
Pi is not equal to 6. It is equal to 3.14159...
