Precalculus Calculator

Guide to Using the Precalculus Calculator

The Precalculus Calculator is a versatile tool designed to handle various mathematical functions related to precalculus. This guide will walk you through the steps needed to effectively use the calculator to perform calculations for exponential, logarithmic, and trigonometric functions.

Step 1: Select the Function Type

Begin by selecting the type of function you want to calculate:

• Exponential Function: Use this option to calculate powers of a number.
• Logarithmic Function: Choose this to calculate logarithms, either using a specified base or natural logarithms.
• Trigonometric Function: This option allows you to calculate sine, cosine, and tangent for a given angle.

Step 2: Enter Required Inputs

Depending on the chosen function type, you will need to enter specific values in the input fields:

For Exponential and Logarithmic Functions

• Base Number: Enter a base number between -1000 and 1000, with increments of 0.1. This field is required for both function types.
• Exponent/Power: Enter an exponent value between -100 and 100, with increments of 0.1. This field is required.

For Trigonometric Functions

• Angle (degrees): Enter an angle between -360 and 360 degrees, with increments of 0.1. This field is optional but necessary for trigonometric calculations.

Step 3: Review the Validation Rules

Ensure that all mandatory fields are filled and that the values conform to the specified range and step. Any missing inputs or out-of-range values will prevent the calculator from functioning correctly.

Step 4: Obtain Results

Once all inputs are correctly entered, the calculator will compute and display the requested results:

Exponential Calculations

• Exponential Result: Displayed using the calculation pow(baseNumber, exponent), this result shows the base number raised to the specified power, formatted to four decimal places.

Logarithmic Calculations

• Logarithm Result: This result, calculated using log(exponent) / log(baseNumber), represents the logarithm of the exponent to the base number, formatted to four decimal places.
• Natural Logarithm: Calculated as log(baseNumber), this result gives the natural logarithm of the base number, formatted to four decimal places.

Trigonometric Calculations

• Sine: Calculated using sin(angle * pi / 180), providing the sine of the angle in degrees, formatted to four decimal places.
• Cosine: Calculated with cos(angle * pi / 180), displaying the cosine of the angle, formatted to four decimal places.
• Tangent: Derived from tan(angle * pi / 180), gives the tangent of the angle, formatted to four decimal places.
• Angle in Radians: Converts the angle from degrees to radians using angle * pi / 180 and displays the result with the ‘rad’ suffix.

By following these steps, you can effectively use the Precalculus Calculator to perform various computations related to precalculus functions. Make sure to carefully enter your inputs and verify results displayed for precision and correctness.
