The formula to find the hypotenuse is the square of the hypotenuse equals the sum of the squares of the base and the perpendicular sides. H² = B² + P² All these calculations are made easier to use and understand with an online trigonometric functions calculator. Real Life ...
Subtract the square of the known side from the square of C. In a triangle with side A as 5 and the hypotenuse as 13, you would subtract 25 from 169, for a difference of 144. Step 3 Take the square root of the difference to find the unknown side: The square root of 144 is 12, ...
Use the given function value(s), and trigonometric identities (including the cofunction identities), to find the indicated trigonometric functions. \cos\theta=\frac{1}{3} The expression sin( ) / 1 - cos( ) can be written as the sum of which two trig functions? Simplify to a...
Compute the exact value of the following sum: \sum_{k=1}^{\infty} \frac{2^k}{5^{k+1 How to find the radius of a circle How do you use a calculator to solve an expression with exponents like B^3 / B^-6. For example, why does the calculator return an unexpected answer ...
When do the domain and range switch in a log function? When its the inverse of a log function What is the log of a product? The sum of the logs What is the log of a quotient? The difference of the logs What does square root translate to? (#)^1/2 money paid for the use of ...
Establishing identities using the double-angle formulas is performed using the same steps we used to derive the sum and difference formulas. Choose the more complicated side of the equation and rewrite it until it matches the other side. Using the Double-Angle Formulas to Verify an Identity Verif...
The area is A = a²/2; and The perimeter equals a(2 + √2) (the sum of the two sides plus the hypotenuse). What are the values of the 6 trig functions at 90 degrees? The values of the 6 trig functions for 90 degrees (π/2) are the following ones: sin(90°) = 1; cos...
