Question

Find the solution
sec60+cos0=​

Answer 1

• sec 60= 2
• cos 0 = 1

> sec 60 + cos 0

> 2 + 1

> 3

Answer 2

To solve this question we have to know the standard values of trigonometric functions. Please refer to the table provided.

we know that

$Cos60 = \frac{1}{2}$

$Cos0 = 1$

from trigonometric relations

$Sec60 = \frac{1}{cos60} \\ \\Sec60 = \frac{1}{\frac{1}{2} }\\ \\ Sec 60 = 2$

Now find the value,

$Sec60+Cos0 = 2+1\\Sec60+cos0=3$

∴The solution of $Sec60+Cos0 = 3$
