I need some to do some work in the area of Calculus... Please let me know if you are a recent graduate or studying Calculus 3 courses... Expert level is required... Max budget is $40.... 30 Hours for the assignment - this is a small assignment... There will be an assignment every week... So, its a continuos work... I only need answers.... The format of the answer should be workable for EXCEL. For example; (16*t+49)^(1/2) (tan((t+6*atan(24))/6))*(1/6) (x^2/2+7)^(1/2) (6*ln(x)+42*x+83)^(1/3)
