What is the Law of Cosines and how is it used in geometry?
The Law of Cosines is a formula used to find the length of a side of a triangle. It states that the square of a side of a triangle equals the sum of the squares of the other two sides minus twice the product of those sides and the cosine of the angle between them.
What are the trigonometric ratios and how are they used in solving problems involving right triangles?
What are the trigonometric ratios and how are they used in solving problems involving right triangles?
The trigonometric ratios are sine, cosine, and tangent. They are used to relate the angles of a right triangle to the lengths of its sides. By using these ratios, you can find missing side lengths and angles of a triangle.
How do you find the equation of a line tangent to a circle at a given point?
How do you find the equation of a line tangent to a circle at a given point?
To find the equation of a line tangent to a circle at a given point, you need to find the slope of the line perpendicular to the radius of the circle at that point. Then, you can use the point-slope form of a line to find the equation of the tangent line.
