Which identity would be best to start with?sin²(t) + cos²(t) = 1✔ tan²(t) + 1 = sec²(t)1 + cot²(t) = csc²(t)
A
sin²(t) + cos²(t) = 1B
✔ tan²(t) + 1 = sec²(t)C
1 + cot²(t) = csc²(t)2

Which identity can you now use to find cos(t)?✔ cos(t) = 1 / sec(t) cot(t) = 1 / tan(t) X tan(t) = sin(t) / cos(t)
A
✔ cos(t) = 1 / sec(t)B
cot(t) = 1 / tan(t)C
X tan(t) = sin(t) / cos(t)Did you find these answers helpful?
