Well, since I am at rest, my velocity is 0. Therefore my mass is not affected by my velocity and is 110 lbs. m=110/ square root of 1-0=110 Math is fun, are you taking a class? I've had many, higher science is all math.
sin2x= 2sinx*cosx cos2x=cosx*cosx - sinx*sinx . . . P of triangle: P=1/2(x1(y2-y3)+x2(y3-y1)+x3(y1-y2))
What's the big deal? Pythagorean theorem gives you the length of the sides of a right triangle. Even the scarecrow from Oz learned that !
Ive taken 600 level math courses, but it has been a long time since Ive been in those classes, so alot of it has excaped my mind right now. I could probably still do some calculus equations for ya yet.
s(emi-perimeter)=(a+b+c)/2 square root of (s(s-a)(s-b)(s-c)) a,b,c being the sides of the triangle and this gives you the area
