Answer 1

Answer: hope this answers your question

Step-by-step explanation:

Answer 2

Answer:

cotA+cosecA-1/cotA-cosecA+1=

convert into sin and cos ratios

(cosA+1-sinA)/(cosA+sinA-1)

multiply (cosA+sinA+1) both numerator and denominator

(1+cosA)^2-sin^2A/2sinAcosA

2cosA+2/2sinA

cot A + cosec A
