About the Trigonometry
What is this right-angled triangle? A triangle in which one angle is 90 degrees and the other two angles are smaller than 90 degrees is called a right-angled triangle.
The side in front of 90 degrees will be the side with the longest length of this triangle, which we call the hypotenuse. There are three angles in a triangle; now, we have shown B as 90 degrees. Now, this triangle also has an unknown angle when we look at it in relative terms. Now the two unknown angles in the triangle are A and C. You can either take the unknown angle at angle C or A. The unknown angle is identified by the name of theta. Theta represents the unknown angle. The side in front of 90 degrees is the hypotenuse; similarly, this unknown angle is represented by theta. The side in front of the theta will always be perpendicular. The side on which the whole triangle rests is called the base. You will have to remember this. A right-angled triangle is formed by the three sides: perpendicular, hypotenuse, and base.
How to Use the Trigonometry Calculator
Values entered: Enter the desired side or angle value to be calculated.
Select Function: Select the desired trigonometric function (such as the tangent, sine, or cosine).
Obtain outcomes: The trigonometric value corresponding to that will be shown on the calculator.
For instance, the sine of thirty degrees would be found by:
Enter: 30
Choose: sine; Outcome: 0.5
