Question

If A=60 degree verify
sec square A - tan square A = 1
PLEASE ANSWER IT FAST

Answer 1

Answer:

Step-by-step explanation:

A= 60 °

sec²A - tan²A = 1

sec 60° = 2 , tan 60° =  √3

2² - √3²

4 - 3 = 1

HENCE , PROVED

Answer 2

Step-by-step explanation:

(sec 60)^2-(tan 60)^2=1

sec 60=2

tan 60= root3

2^2-root3^2=1

4-3=1

1=1

hence proved
