Do we have trigonometry in class 12?
CBSE Class 12 mathematics contains Inverse Trigonometric Functions. This chapter includes definitions, graphs and elementary properties of inverse trigonometric functions. Trigonometry formulas for class 12 play a critical role in these chapters. Hence, all trigonometry formulas are provided here.
What are the properties of inverse trigonometry?
Important Properties of Inverse Trigonometric Functions
- Sin−1(x) = cosec−1(1/x), x∈ [−1,1]−{0}
- Cos−1(x) = sec−1(1/x), x ∈ [−1,1]−{0}
- Tan−1(x) = cot−1(1/x), if x > 0 (or) cot−1(1/x) −π, if x < 0.
Is 11th math related to 12th?
Yes it is . 11th maths is the basics which will get used in 12th .
How do you find the inverse of a function in CBSE 12?
To find the inverse of a rational function, follow the following steps….An example is also given below which can help you to understand the concept better.
- Step 1: Replace f(x) = y.
- Step 2: Interchange x and y.
- Step 3: Solve for y in terms of x.
- Step 4: Replace y with f-1(x) and the inverse of the function is obtained.

- cosθ=1secθ;cosθsecθ=1 θ = 1 sec θ = 1.
- tanθ=1cotθ;tanθcotθ=1 θ = 1 cot
What is the formula for inverse trigonometric functions?
The inverse trigonometric functions are written as sin -1 x, cos -1 x, cot -1 x, tan -1 x, cosec -1 x, sec -1 x. Now, let us get the formulas related to these functions.
What are the six essential trigonometric functions?
These ratios are also known as trigonometric functions and mostly use trigonometry all formula. The six essential trigonometric functions are sine, cosine, secant, cosecant, tangent, and cotangent. The trigonometric functions and identities are derived by using the right-angled triangle.
What are the basic formulas in trigonometry?
In Trigonometry Formulas, we will learn Basic Formulas sin, cos tan at 0, 30, 45, 60 degrees Pythagorean Identities Sign of sin, cos, tan in different quandrants Radians Negative angles (Even-Odd Identities) Value of sin, cos, tan repeats after 2π Shifting angle by π/2, π, 3π/2 (Co-Function Identities or Periodicity Identities)
Why are the ratios of trigonometry inverted?
The ratios of trigonometry are inverted to create the inverse trigonometric functions. sinθ = x and θ = x . So, x can have the values in whole numbers, decimals, fractions or exponents.
