30 degrees explanation 2Cosx-radical 3=0 Then 2cosx=radical 3 and cos x=(radical 3)/2 Now remember that cos 300 is (radical 3)/2 from the 30/60/90 triangle. So the answer is 30 degrees.
The answer is cos A . cos A = 1/ (sec A)
It depends on what identity you are talking about whether its multiplicative inverse to additive inverse i mean you have to be more specific
Inverse sine is defined for the domain [-1, 1]. Since 833 is way outside this domain, the value is not defined.
