Eh, who needs accuracy?

sin(30) x 2

3-3x6+2

It's 2, since 3-3=0, 0 x 6 = 0, 0 + 2 = 2. BOOM DONE.

Hmm... tan(90)

The answer to the previous one is -13. 3-3*6+2 by order of operations is 3-(18)+2 = -15+2 = -13

The answer to yours is DNE (does not exist)

1

Now for my question: sin(x) = [sqrt(2)]/2 ; solve for x in either degrees or radians

Your answer is correct, it can just be simplified a bit more. Sqrt root of 20 can go to 2 sqrt of 5 which then makes the answer -2 +- (2)sqrt 5/2. So the two separate answers would be sqrt(5)/2 and -2 sqrt(5)

6/65

x = 45 degrees

Question/Challenge (Tougher): Derive the formula for the circumference of a circle using the limit of the perimeter of regular polygons.

Focus on the isosceles triangles regular polygons make when their radius (center to outer vertices) is drawn...

Question/Challenge (Easier): 2^x + 5 = 13... Solve for x

Wow, what a bunch of nerds. I'm 2 kool for skool

wrong, this is according to PEMDAS

Correct

No question? Well okay then. For my next question:
Solve Reimann's Hypothesis. (I'm such a jerk lol)
