What is the exact value of the expression cos 7pi over 12 cos pi over 6 -sin 7pi over 12 sin pi over 6?
cos(a)cos(b)-sin(a)sin(b)=cos(a+b) a=7pi/12 and b=pi/6 a+b = 7pi/12 + pi/6 = 7pi/12 + 2pi/12 = 9pi/12 We want to find cos(9pi/12) cos(9pi/12) = cos(3pi/4) cos(3pi/4)= cos(pi-pi/4) cos(pi)cos(pi/4)-sin(pi)sin(pi/4) cos(pi)=-1 sin(pi)=0 cos(pi/4) = √2/2 sin(pi/4) =√2/2 cos(pi)cos(pi/4)-sin(pi)sin(pi/4) = - cos(pi/4) = -√2/2
What is 6 times pi?
If pi=3.1416, then 6×3.1416=18.8416
What is 2 pi over 2?
2 pi / 2 = pi.
What is the reciprocal of pi over two?
(pi/2)-1 = 2/pi
What is the 42nd digit of Pi?
The 42nd digit of pi is 6. (The first 43 digits of pi are 3.141592653589793238462643383279502884197169. If pi were rounded to the nearest 42 digits, then the 6 would be rounded up to a seven.)
What is 6 over 7 minus 1 over 3?
pi squared
What is the exact value of the expression cos 7pi over 12 cos pi over 6 -sin 7pi over 12 sin pi over 6?
cos(a)cos(b)-sin(a)sin(b)=cos(a+b) a=7pi/12 and b=pi/6 a+b = 7pi/12 + pi/6 = 7pi/12 + 2pi/12 = 9pi/12 We want to find cos(9pi/12) cos(9pi/12) = cos(3pi/4) cos(3pi/4)= cos(pi-pi/4) cos(pi)cos(pi/4)-sin(pi)sin(pi/4) cos(pi)=-1 sin(pi)=0 cos(pi/4) = √2/2 sin(pi/4) =√2/2 cos(pi)cos(pi/4)-sin(pi)sin(pi/4) = - cos(pi/4) = -√2/2
What is secant pi over 6?
It is 2*sqrt(3)/3.
What is 17pi over 6 minus 2 pi?
Use the distributive property: 17pi/6 - 2pi = (17/6 - 2) pi. Now, just subtract the fractions as you normally would.
What is the diameter of a circle if the circumference is 6 pi?
The circumference is: 6*pi/pi = 6 units
What is 6 times pi?
If pi=3.1416, then 6×3.1416=18.8416
What is the answer to inverse tangent square root 3 over 3?
30 degrees or pi/6
What is the area of a circle whose diameter is 6 feet?
diameter = 2 Pi R = 6 ft so R=diameter/(2 pi) area = Pi R² = Pi x diameter²/(2² pi²)=6²/(4 pi)
What is the diameter of a 6 circumference?
Circumference = 2(pi)r OR (pi)d Taking (pi)d = 6 d=6/(pi) d=1.91 (3 significant figures)
What is the area of a circle when the circle is 6 ft?
Is the radius 6ft? If so, then area = pi*r^2 = pi * (6)^2 = 36 * pi If the diameter is 6ft, then area = pi * (6/2) ^2 = 9 * pi
What is the circumference of a circle with a diameter of 6?
Since circumference equals pi times the diameter, if the diameter of a circle is 6, then its circumference is going to be pi times 6 or 6 pi.
What is 2 pi over 2?
2 pi / 2 = pi.
