Use the function abs().
For example, type in abs(-6) to get 6
.
There are two positive solutions that can be obtained numerically as follows:
There is also a negative solution that could be obtained by the bisection method (x ≈ -0.82667)
Like so:
8C5 = 8!/((8-5)!*5!) → 8!/(3!*5!) → 8*7*6*5!/(3!*5!) → 8*7*6/(3!) → 8*7*6/6 → 8*7 → 56
You haven't shown the formula!!
22+(n-1)*200
This is arcsine or asin. It can be obtained by pressing the 2nd button first, then asin appears.
Here's a numerical solution:
There are some values of theta for which it is true. I guess the aim is to find those values.
The two sides are not generally equal!
Try a few example values (say 20 and 25 degrees) to check.
