Inverse of tan
Memorise the basic formula of sec, cos and cot.
If the tangent is √3, then first find the value the sine of the angle.
The cotangent (cot) of an acute angle in a right triangle is a ratio. It is the length of the adjacent leg (adj) divided by the length of the opposite leg (opp).
If the sine of theta is 4/5, then the cosine of theta can be found using the Pythagorean identity.
We are given cos α = 4/7, Recall that cot α = 1/tan α. Use the Pythagorean identity for sine and cosine to find tan α. Use the relationship between cot α and tan α
The secant (sec) of an acute angle in a right triangle is a ratio. It is the length of the hypotenuse (hyp) divided by the length of the adjacent leg (adj). The hypotenuse is the side across from the right angle and the adjacent leg is the leg next to the specified angle.
The cotangent function (cot) can be expressed as the reciprocal of the tangent function.
Since secant is the reciprocal of cosine, if the secant is 5/2, then the cosine of the angle is 2/5. Using the Pythagorean identity, we can find that the sine of the angle
The secant (sec) of an acute angle in a right triangle is a ratio. It is the length of the hypotenuse (hyp) divided by the length of the adjacent leg (adj).
