# How To Input Sin^2 In Calculator – Solved By Experts

Is the scientific calculator one of the greatest inventions of all time? We think so! And, we are sure that math students, accountants, **professionals in real estate**, and financial experts will agree.

**How To Input Sin^2 In Calculator?**

A significant upgrade on the regular calculator, the **scientific calculator** helps solve complex problems within seconds and get answers in a jiffy. It takes away all the headache from calculations, which is crucial, especially during exams and time-sensitive jobs.

Now, you can only take advantage of the calculator if you are able to use it properly. There is a learning curve, of course, and this varies with the applications and what formulae you have to use. You may come across multiple questions and doubts when you first use your scientific calculator. Today, we will address one of the most common ones.

**How To Input Sin^2 In A Calculator?**

Sin^2 is basically a double angle formula. It can be confusing because you can’t directly input it. But hey, we have solved this problem for you.

- One of the easiest ways to input Sin^2 is to type in (Sin(x))2
- If you are using a
**graphing calculator**, here’s what you add – Sin(x)^2=(Sin(x))^2 - Another way to input Sin^2 in a scientific calculator is to enter X > Press Sin > Press the Squared button

We understand the stress you must have gone through trying to figure out the solution and we are glad you found us.
