How can I find the derivative of f(x)=e^(1/x^2) from first principles (ie limit as h->0)?-1) f(x) = e^(1/x²); ==> f(x+h) = e^{1/(x+h)²}
2) So, f(x+h) - f(x) = e^{1/(x+h)²} - e^(1/x²) = e^(1/x²)[e^{1/

help??--3 and -16-let x & y be the two nmbers.
xy = 48 ............ equation (1)
x + y = –19
y = –x - 19 ............... equation (2)
plug in value of y in eq (2) into eq (1);
x ( –x - 19 ) = 48
