The domain of the arccosine function is just the same with the arcsine function but its range is from 0 to +180°. To use this function, just click the “acos” button of this scientific calculator. The inverse cosine (arccosine) trigonometric function can be used to determine the angle of a cosine value. The domain of an inverse sine function is from -1 to +1 and the range is from -90° to +90°. This can be used in this scientific calculator by clicking the “asin” button. The inverse sine (arcsine) trigonometric function can be used to determine the angle of a sine value.
The cotangent function is a reciprocal of the tangent function. This function can be used in this scientific calculator by clicking the “tan” button. The tangent function relates the angle of a right-angled triangle to the ratio of the length of the side opposite the angle and the side adjacent to the angle. The secant function is a reciprocal of the cosine function. It can be used in this scientific calculator by clicking the “cos” button. The cosine function is another trigonometric function that can be used to relate the angle of a right triangle to the ratio of the length of the side adjacent to the angle and the hypotenuse. The cosecant function is a reciprocal of the sine function. The sine function can be used in this scientific calculator by clicking the “sin” button. In a right-angled triangle, the sine function can be used to relate the angle to the ratio of the length of the side opposite the angle and the hypotenuse. Here are the trigonometric functions that you will encounter as you study mathematics and engineering: It could be as simple as solving an unknown value of a right-angled triangle or solving the instantaneous power absorbed by an electrical element. Trigonometric functions: In mathematics and in various fields of engineering, trigonometric functions are frequently used to solve different problems. Which is supposedly called an “obelus” - who knew? (x / y) Division, sometimes referred to as the quotient, is sometimes shown as a fraction, a “/” or the “÷” symbol. (x * y) Multiplication, the product or “times” is represented sometimes by an “x” and sometimes by an asterisk “*”. (x - y) Subtraction, the “minus” sign, or sometimes difference, is used to find the numerical separation between two numbers, thus the term “difference”. (x + y) Addition, also known as summing or, more colloquially, “plus” is used to sum numbers together.
