How to write sin 2 in calculator

In particular, sin ⁡ ( A) 2 means sin ⁡ ( A 2). It should be noted, though, that the convention for multiplying trig functions works a little differently than the other conventions. An expression like sin ⁡ x cos ⁡ x means ( sin ⁡ x) ( cos ⁡ x) and not sin ⁡ ( x cos ⁡ x).

Sine Calculator. Trigonometric sine calculator. In order to calculate sin(x) on the calculator: Enter the input angle. Select angle type of degrees (°) or radians (rad) in the combo box. Press the = button to calculate the result.

(So, for instance, sin ⁡ ( sin − 1 ⁡ ( x)) = sin − 1 ⁡ ( sin ⁡ ( x)) = x. But sin 2 ⁡ ( sin − 1 ⁡ ( x)) = x 2, not sin ⁡ ( x) .) However, exponents (other than − 1) never seem to be used that way with respect to trig functions. Perhaps someone could explain the history of how this inconsistency came about. Are sin²x and (sinx)² the same?

To calculate sec 2. ⁡. x on a graphing calculator, you should have the ability to write strings of functions with parenthesis and the like and can write it as: 1 / ( cos. ⁡. ( x)) 2. If you are using a scientific calculator, then you could push the buttons in the following order: inputnumber for x, cos, x 2, x − 1.
