If cosec A=√10,find the value of all t-ratio of theta?
Given,
Cosec A = root 10 = H/P
So,
We use Pythagoras theorem, we have
H^2 =P^2 + B^2
1^2 - root 10^2 = B^2
9 = B^2
3 = B
So, sin A = 1/root 10
Cos A= 3/ root 10
Tan A = 1/3
Cot A = 3
Sec A = root 10 /3
If cosec A=√10,find the value of all t-ratio of theta?
Problem: If cosec A=√10, find the value of all t-ratio of theta.
Solution:
To solve the problem, we need to find the values of all six trigonometric ratios of angle A, given cosec A=√10. Let's use the following formulae:
- cosec A = 1/sin A
- sec A = 1/cos A
- tan A = sin A/cos A
- cot A = cos A/sin A
- sin^2 A + cos^2 A = 1
- 1 + tan^2 A = sec^2 A
- 1 + cot^2 A = cosec^2 A
Step 1: Find sin A
cosec A = 1/sin A
√10 = 1/sin A
sin A = 1/√10
sin A = √10/10
Step 2: Find cos A
sin^2 A + cos^2 A = 1
cos^2 A = 1 - sin^2 A
cos^2 A = 1 - (10/100)
cos^2 A = 9/10
cos A = ± √(9/10)
Since A is an acute angle, cos A is positive.
cos A = √(9/10)
cos A = 3/√10
cos A = 3√10/10
Step 3: Find tan A
tan A = sin A/cos A
tan A = (√10/10) / (3√10/10)
tan A = (√10/10) * (10/3√10)
tan A = 1/3
Step 4: Find cot A
cot A = cos A/sin A
cot A = (3√10/10) / (√10/10)
cot A = 3
Step 5: Find sec A
sec A = 1/cos A
sec A = 1 / (3√10/10)
sec A = 10/3√10
Step 6: Find cosec A
cosec A = √10
Step 7: Summarize the values of all six trigonometric ratios
sin A = √10/10
cos A = 3√10/10
tan A = 1/3
cot A = 3
sec A = 10/3√10
cosec A = √10
Therefore, the values of all six trigonometric ratios of angle A are sin A = √10/10, cos A = 3√10/10, tan A = 1/3, cot A = 3, sec A = 10/3√10, and cosec A = √10.
