I would to know these answer of the questions

1. Calculate the limit: lim M (Si 1 -+ 0o i= 1 2. Using the right endpoint approximation , compute the approximation for f(x) = sin(xx) on the interval [1,2] with n = 50 subintervals. (Make sure your calculator/software is in radian mode --not degrees.) Round your answer to the one-hundred thousandths place--5 decimal places after the decimal point. 3. Use the Fundamental Theorem of Calculus (Part 1) to compute the following: d . RX2 cos-(t) dt dx J xX 4. Using antiderivatives, calculate the following: 3 1/3 dx 4
