Calc HW

Need these 20 calculus problems solved, with all work shown, and answers circled.Need them back tomorrow evening, by 6PM Mountain Time. I will NOT take business off this site. Scam artists like “Proffesor Stein” have ripped me off before, and I will not trust work I cannot be refunded for if I don’t receive any of the work I pay for..Do NOT send a handshake unless you’ve LOOKED AT THE ATTACHED PROBLEM SET and are 100% sure you can get at least 18/20 problems. Less than an A is not acceptable. Need calculus experts only.Thanks.
