Our math problem solver that lets you input a wide variety of trigonometry math problems and it will provide a step by step answer. This math solver excels at math word problems as well as a wide range of math subjects.
Here are example math problems within each subject that can be input into the calculator and solved. This list is constanstly growing as functionality is added to the calculator.
Below are examples of basic math problems that can be solved.
Math word problems require interpreting what is being asked and simplifying that into a basic math equation. Once you have the equation you can then enter that into the problem solver as a basic math or algebra question to be correctly solved. Below are math word problem examples and their simplified forms.
Word Problem: Rachel has 17 apples. She gives some to Sarah. Sarah now has 8 apples. How many apples did Rachel give her?
Simplified Equation: 17 - x = 8
Word Problem: Rhonda has 12 marbles more than Douglas. Douglas has 6 marbles more than Bertha. Rhonda has twice as many marbles as Bertha has. How many marbles does Douglas have?
Variables: Rhonda's marbles is represented by (r), Douglas' marbles is represented by (d) and Bertha's marbles is represented by (b)
Simplified Equation: {r = d + 12, d = b + 6, r = 2 �� b}
Word Problem: if there are 40 cookies all together and Angela takes 10 and Brett takes 5 how many are left?
Simplified: 40 - 10 - 5

In geometry, trigonometry questions ask students to solve a variety of problems including multi-step problems and real-life problems. We also need to be familiar with the exact values of the trigonometric functions at certain angles. We look at applying trigonometry to 3D problems as well as using the sine rule, cosine rule, and area of a triangle.
Problem 14 sent by Vasa Shanmukha Reddy. If cot (x) = 2 then find \displaystyle \frac { (2+2\sin x) (1-\sin x)} { (1+\cos x) (2-2\cos x)} (1+cosx)(2 −2cosx)(2+2sinx)(1−sinx) Problem 15.

Correct answer: 23.81 meters. Explanation: To make sense of the problem, start by drawing a diagram. Label the angle of elevation as 25 o, the height between the ground and where the wire hits the flagpole as 10 meters, and our unknown, the length of the wire, as w. Now, we just need to solve for w using the information given in the diagram.
Practice Questions on Trigonometry. Solve the following trigonometry problems. Prove that (sin α + cos α) (tan α + cot α) = sec α + cosec α. If ∠A and ∠B are acute angles such that cos A = cos B, then show that ∠A = ∠B. If sin θ + cos θ = √3, prove that tan θ + cot θ = 1. Evaluate: 2 tan 2 45° + cos 2 30° - sin 2 60°.
In KS4 maths, trigonometry questions ask students to solve a variety of problems including multi step problems and real life problems.
