Answer:
sin-1 (–x) = – sin-1 x.
cos-1 (–x) = π – cos-1 x.
tan-1 (–x) = – tan-1 x.
cosec-1 (–x) = – cosec-1 x.
sec-1 (–x) = π – sec-1 x.
cot-1 (–x) = π – cot-1 x.
Step-by-step explanation:
sin-1 (–x) = – sin-1 x.
cos-1 (–x) = π – cos-1 x.
tan-1 (–x) = – tan-1 x.
cosec-1 (–x) = – cosec-1 x.
sec-1 (–x) = π – sec-1 x.
cot-1 (–x) = π – cot-1 x.
