Answer:

see explanation

Step-by-step explanation:

Using the identities

sec x = [tex]\frac{1}{cosx} [/tex]  ,  csc x = [tex]\frac{1}{sinx} [/tex]

sin²x + cos²x = 1

Consider the left side

[tex]\frac{cos0}{sec0} [/tex] + [tex]\frac{sin0}{csc0} [/tex]

= [tex]\frac{cos0}{\frac{1}{cos0} } [/tex] + [tex]\frac{sin0}{\frac{1}{sin0} } [/tex]

= cos²Θ + sin²Θ

= 1 = right side , thus proven
