Detailed Solution for Test: Advanced Trigonometric Formula - Question 1

Test: Advanced Trigonometric Formula - Question 2

### Find tan 40° ?

Detailed Solution for Test: Advanced Trigonometric Formula - Question 2

Test: Advanced Trigonometric Formula - Question 3

### Find the value of 1 + cos2A.

Detailed Solution for Test: Advanced Trigonometric Formula - Question 3

By formula

Cos 2A = Cos²A-Sin²A

Cos²A-Sin²A=Cos²A-(1-Cos²A) =Cos²A -1 +Cos²A=2 Cos²A - 1

so, Cos 2A = 2 Cos²A - 1

Test: Advanced Trigonometric Formula - Question 4

What is the value of cos 4x ?

Test: Advanced Trigonometric Formula - Question 5

What is the value of cos 6X?

Test: Advanced Trigonometric Formula - Question 6

3 Sin 10° – 4 Sin3 10° = ?

Detailed Solution for Test: Advanced Trigonometric Formula - Question 6

3sinA-4sin3A=sin3A
Given, 3 sin 10° - 4 sin 3 10°
So, sin3A i.e sin 30
= ½

Test: Advanced Trigonometric Formula - Question 7

=

Test: Advanced Trigonometric Formula - Question 8

Test: Advanced Trigonometric Formula - Question 9

In a triangle ABC, sin 2A = ?

Detailed Solution for Test: Advanced Trigonometric Formula - Question 9

Test: Advanced Trigonometric Formula - Question 10

In a triangle ABC, if angle A = 72°, angle B = 48° and c = 9 cm then the Ĉ is

Detailed Solution for Test: Advanced Trigonometric Formula - Question 10

In any traingle The sum of 3 sides of a traingle is equal to 180°

Given

A=72°

B=48°

A+B+C=180°

72°+48°+C=180°

C=180°-120°

C=60°
