Integer numbers (positive, negative, and O) are allowed. Below are some examples. Example Math Expression How to Enter the Answer 2 -3/5 infinity 2\"8+l 2+exp(5) 5*pi/9 4/7-3*ln (2) sqrt(2) 5"(l/3) sqrt(5exp(3)+2*ln(7*pi)) fac(5) Problem #4: Let f(x) = (sin '(Vx )) 2. Find f'( 1). 4*sin^-1*(1/2)/sqrt(3) Enter your answer symbolically, Problem #4: as in these examples Your answer cannot contain the sin (4(sin)I INI- function! V3Answer Format Unless otherwise noted, enter answers as: - Whole Numbers - Exact Fractions (e.g., 2/3 or -5/4) or (only when necessary): - Decimals correct to six decimal places The use of decimal numbers is discouraged because decimal numbers are subject to rounding errors, which could cost you marks!
