Which is greater 1 over 2 or 3 over 13?
1/2 think of it like a pizza pie. 1/2 would be half of the entire pie. however, 3 / 13 would be 3 slices if the pie was cut into 13 slices. clearly, 1/2 is larger.
What is 1 over 9 doubled?
1/9 doubled is 2/9. Consider a pie cut into 9 pieces. 1/9 is one piece of pie. Double that top get 2 pieces of pie or 2/9.
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
Verify that sin minus cos plus 1 divided by sin plus cos subtract 1 equals sin plus 1 divided by cos?
[sin - cos + 1]/[sin + cos - 1] = [sin + 1]/cosiff [sin - cos + 1]*cos = [sin + 1]*[sin + cos - 1]iff sin*cos - cos^2 + cos = sin^2 + sin*cos - sin + sin + cos - 1iff -cos^2 = sin^2 - 11 = sin^2 + cos^2, which is true,
What is the value sin x if cos x equals 2 over sqrt 5?
It would be 1 over square root 5.
What is the sin of negative pie over 2?
-1
What is the sin of 2 pie?
sin(2*pi) - not pie - is the same as sin(0) = 0
What is the sin of pie over 9?
1/3
What does sin pie over three equal?
one half
What is sin pie divided by six equals one half?
Sin(pi/6) = 1/2 is a true statement [not pie].
What is the sin pi over 2?
sin(pi/2)=1
What is sine of 3 pie divided by 4?
0.75
What is sin of 3 pi over 2?
sin pi/2 =1 sin 3 pi/2 is negative 1 ( it is in 3rd quadrant where sin is negative
What is the value of sin 3 pi over 2?
sin(3π/2) = -1
What is the sine s of pie over 2?
1
What is the exact value of tan pie over 2?
1
