Question

11. Calculate sin45º.cosec45° + cos45º.sec45° + tan45º.cot45°​

Answer 1

Answer:

3

Step-by-step explanation:

sin45.cosec45 = 1

cos45.sec45 =1

tan45.cot45=1

hence 1+1+1=3

plz follow

Answer 2

Step-by-step explanation:

sintheta x cosectheta=1

costheta × sectheta =1

tantheta * cottheta=1

sin45º.cosec45° + cos45º.sec45° + tan45º.cot45°

=1+1+1

3

or

sin45º.cosec45° + cos45º.sec45° + tan45º.cot45°

=(1/root2) * root2 + 1/root2) * root2 + 1*1

=1+1+1=3
