Draw a graphic window vertically in two parts and draw a graphic in the left part
functions f1 (x) with dashed line of black color, and in the right function f2 (x) by crosses
green color. Observe the variable x in the interval [-pi/4, pi/4]
f1(x)= sin^4(x^2+1) / (3^x + e^(x+1))^1/3
f2(x)=2e^xlog10(4/x+3) + 1/(x+1)
Here is what i wrote, y1 and y2 i think i made mistake there, but i am nost sure. I would be thankful if you correct me , sorry for bad engilsh.
y1= sin(x^2+1).^4 / (3^x + exp(x+1)).^ (1/3)
y2=2*explog10(4./x+3) + 1./(x+1)
