Question 1066029
s=e^t+tan (t)
I'm assuming t is in radians.
e^(0.25)*tan(.25)=0.3279
e^0.26* tan(.26)=0.3450
e^0.251*tan(.251)=0.3296
e^0.2501*tan(.2501)=0.3280
so s(.26)-s(.25) all divided by 0.01 is 1.71
s(.251)-s(.25) divided by 0.001 is 1.69749
s(.2501)-s(.25) divided by 0.0001=1.69579
The actual derivative is tan(t)*e^t+e^t*sec^2(t)
this is tan(.25)*e^(0.25)*.25+e^(.25)*1/cos^2(.25)=1.69561
