As follows: \(\frac{1-\cos^2\theta}{\sin\theta} \rightarrow \frac{\sin^2\theta}{\sin\theta} \rightarrow \sin\theta\)
.
A pentagon is two-dimensional and has zero volume!!
sin(45°) can be written as 1/sqrt(2), which, in turn, is the same as sqrt(2)/2, so 12*sin(45°) is 12*sqrt(2)/6 or 6*sqrt(2).
As follows:
\(\frac{u^3-3u^2+2u}{u^2-1}\rightarrow \frac{u(u-1)(u-2))}{(u+1)(u-1)}\rightarrow \frac{u(u-2)}{u+1}\)
Here are some rational approximations to pi with decimal equivalents given to 9 decimal places:
I'm wrong! There is an i, but you have to press the 2nd button first to see it.
No, but you can enter the letter i. For example the calculator accepts (1+2i)*(3+4i)
For normal distribution with mean 0 and standard deviation of 1, then
a. K = -0.44
b. K = 0.56
Can you provide more details of the S-shape in question?
Pythagoras'stheorem says the square on the hypotenuse of a right triangle is equal to the sum of the squares on the two adjacent sides.
