Question

Find the value of cosec10 - root3sec10.

Answer 1

Solutions 

cosec(10) - root(3) sec(10) = 5.759 - (1.732).(1.015) 
cosec(10) - root(3) sec(10) = 5.759 - 1.759 
cosec(10) - root(3) sec(10) = 4.753654497  

Rounded answer = 5 

Answer 2

Answer:

$cosec10 - \sqrt{3}sec10$ is 3.99

Step-by-step explanation:

Given :$cosec10 - \sqrt{3}sec10$

To Find : Solve $cosec10 - \sqrt{3}sec10$

Solution :

$cosec10 - \sqrt{3}sec10$ --- A

$cosec 10 = 5.75877048314$

$Sec 10 =1.01542661189$

$\sqrt{3}=1.73205080757$

Substitute the values in A

$=5.75877048314 -(1.73205080757)(1.01542661189)$

$=3.99$

Hence $cosec10 - \sqrt{3}sec10$ is 3.99
