Solving for x
((2X-14Cos45)/(49+X^2-14XCos45))+0.3536 = 0 Solve to find the value of X Change cos 45 to sqrt 2 and rewrite the equation in the form a x^2 + bx + c = 0 Start out by rewriting it as 2x - 9.8995 = (-0.3536)(49 + x^2 - 9.8995 x) Conimue until you get the form a x^2 + bx + c = 0...

solving for x
y=e^x how do i solve for x. i use the LN process right. i forgot how to do that ln(e ^ x) = x Leo, you have merely stated an identity. David was solving y = e^x for x, which would be x = ln y Thanks reiny.

cubic equation solving
IF there is a rational real root, it is q/p, where p and q are integer factors of the x^3 term and the constant term. Once you have one root (by trial and error), the others can be obtained by solving the quadratic you get by factoring out the first root. In your case, one of ...
