How is 4-4sinx all to the power of 1.5 equal to 8 cosx power of 3?

It is not!
For example, if x = 45 deg or pi/4 radians, then
sin(x) = 1/sqrt(2)
so [4-4sin(x)] = 4*[1-1/sqrt(2)]
and then [4-4sin(x)]1.5 = 1.2681
while
cos(x) = 1/sqrt(2)
so 8cos(x) = 8/sqrt(2) = 4*sqrt(2)
so that [8cos(x)]3 = 181.02

How do you express the term 1-csc squared x all over sin x cot x to cos x?
(1 - csc2x)/(sinx*cotx) = -cot2x/sinxcotx = -cotx/sinx = -(cosx/sinx)/sinx = -cosx/sin2x = -cosx/(1-cos2x) = cosx/(cos2x - 1)
Does 25 to the first power equal 25?
yes. All numbers to the 1st power equal themselves
Find all values of x that satisfy the condition cosx equals 0 where 0degrees is less than or equal to x is less than 360degrees?
cos x = 0; 0 ≤ x ≤ 360° x = 90° or x = 270° ( 90° + 180°)
Determine exact solution for cosx minus 0.5 equals 0?
X=60 how did you get that? could you show all the steps?
Is Anything to the power of zero 0?
No. All real numbers, when raised to the power zero, are equal to 1. Even zero to the zero is equal to 1.

Which branch of your government has more power or do they have equal power?
they are all equal
What is one to the 8 power?
One to any power is equal to 1. As a formula: For all x, 1x = 1.One to any power is equal to 1. As a formula: For all x, 1x = 1.One to any power is equal to 1. As a formula: For all x, 1x = 1.One to any power is equal to 1. As a formula: For all x, 1x = 1.

How do you solve sin squared theta plus cos theta equals sin theta plus cos squared theta?
For simplicity's sake, X represent theta. This is the original problem: sin2x+ cosX = cos2X + sinX This handy-dandy property is key for all you trig fanatics: sin2x+ cos2x = 1 With this basic property, you can figure out that sin2 x=1-cos2x and cos2x= 1-sin2x So we can change the original problem to: 1-cos2x+cosx = 1-sin2X + sinX -cos2x + cosx =-sin2x + sinX Basic logic tells you that one of two things are happening. sin2x is equal to sinx AND cos2x is equal to cosx. The only two numbers that are the same squared as they are to the first power are 1 and 0. X could equal 0, which has a cosine of 1 and a sine of 0, or it could equal pi/2, which has a cosine of 0 and a sine of 1. The other possibility whatever x (or theta) is, it's sine is equal to its cosine. This happens twice on the unit circle, once at pi/4 and once at 5pi/4. If you're solving for all possible values for x and not just a set range on the unit circle, then the final solution is: x=0+2pin x=pi/2+2pin x= pi/4 +2pin x=5pi/4+2pin (note that n is a variable)
