x(t) = 2 + In(7 + t) y(t) = 6 . t2 - 2 . t + 3 Represent the LENGTH of the this parametric curve for 0 s t s 4 as a definite integral LENGTH = dx Then use your calculator to evaluate the integral as a decimal number (rounded to 2 decimal places). LENGTH = Use sqrt(1+x^3) for V 1 + 23 Remember: for trig functions you must be in radian mode
