Answer 2

Answer:

Step-by-step explanation:

tanA + cotA =

sinA/cosA  + cosA/sinA = (sin²A + cos²A)/sinAcosA=1/sinAcosA

    as sin²A+cos²A=1

tanA + cotA+1 = 1/(sinAcosA)  +1

(sinA-cosA)×(1/(sinAcosA)  +1) = 1/cosA +sinA -1/sinA -cosA

                                                 =secA +(1/cosecA)-cosecA-(1/secA)

                                                 =

(sec²AcosecA+secA-cosec²AsecA-cosecA)/cosecAsecA

multiply denominator and numerator by cosecAsecA

and   use cosec²A+sec²A=coescAsecA
