How do you reference a triangle?
Space and AstronomyHow do you find the reference of a triangle? To form the reference triangle, simply drop a perpendicular from the terminal ray of the angle to the x-axis, forming a right triangle. In the first quadrant, the standard position angle is its own reference angle and is contained in the reference triangle. You are now
What is the difference between tan and inverse tan?
Space and AstronomyInverse tan is the inverse function of the trigonometric function ‘tangent’. It is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle. Based on this function, the value of tan 1 or arctan 1 or tan 10,
