Type 0.85 and then press the key cos^(-1) given at the bottom side. And then press sin given at bottom side. By this you will get the answer of sin[cos^(-1)(0.85)]

Just follow the reverse sequence.

Hii

To solve the above sum on the virtual calculator we need to inside out i.e put cos first,then press on sin button, then add powers and complete the brackets.

You will get your desired answer.

I hope this helps. In case of doubt you can freely ask again.

Thanks!!!
