A:

Q: Find sin 0 and tan 0. cos e = sine = tane

A: Given :               cos θ = 25Then hypotenuse = 5 , adjacent = 2 and opposite = ?   To find the…

Q: cos - I resulted in a negative answer. Why is it impossible for cos to be 12 negative?

A: Let's find.

Q: If cos A = -12/13, Pi < A < 3pi/2 and Cot B = 4/3,  0 < B < pi/2, find Cos (A-B)

A: Now by using the identity

Trigonometric Identities

Trigonometry in mathematics deals with the right-angled triangle’s angles and sides. By trigonometric identities, we mean the identities we use whenever we need to express the various trigonometric functions in terms of an equation.

Inverse Trigonometric Functions

Inverse trigonometric functions are the inverse of normal trigonometric functions. Alternatively denoted as cyclometric or arcus functions, these inverse trigonometric functions exist to counter the basic trigonometric functions, such as sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (cosec). When trigonometric ratios are calculated, the angular values can be calculated with the help of the inverse trigonometric functions.
