Welcome to the trigonometry practice section! Here you will find various exercises and problems to help you master the basics of trigonometry.

Exercises

  1. Find the sine of an angle.

    • Given angle A, find sin(A).

  2. Calculate the cosine of a right triangle.

    • If the hypotenuse is 5 units and one leg is 3 units, calculate cos(A).

  3. Solve for missing sides and angles in a triangle.

    • Given a triangle with sides a = 3 units, b = 4 units, and angle C = 60 degrees, find the missing sides and angles.

Practice Problems

  1. Solve for x in the following equation: [ \sin(x) = 0.5 ]

  2. Find the measure of angle A in a right triangle with a = 3 units and b = 4 units.

  3. Calculate the area of a triangle with base b = 6 units and height h = 8 units.

Tips

  • Always start by drawing a diagram of the problem.
  • Use the Pythagorean theorem to solve for missing sides in right triangles.
  • Practice makes perfect! The more you practice, the better you will understand trigonometry.
