If your instructor permits calculator use in this class, then yes, then the answer is yes. If it is no, and you are forbidden from using a calculator, then the answer is no.
Work Step by Step
Some instructors allow this and others do not. Some have concerns about academic integrity and others just want you to know how to think through concepts without a calculator. Always be sure to ask if the policy is not clearly stated. The syllabus usually has this information. In some cases, calculators may be allowed on homework but not exams, or vice versa. This is why it is important to clarify!
