is differentiation is homogeneous then solve (x^2 + y^2) * dx = 2xy * dy
2√12−√27+5√75
1. Prove by direct method:
Suppose x and y are integers. If x and y are odd, then xy is odd.
\sum _{n=3\:}^{\infty }\frac{e^{4n}}{(n-2)!} convergence or divergence
1.55x - 5.93 = -1.47x + 7.9
If 2x+1/3y=5 then find (3x+1/2y)²
If 213
2x+3y-z=7
4x-y+5z=1
-x+2y+3z=12
solve by elimination
