Question

prove that cosA÷(1+sinA)+(1-sinA)÷cosA=2 (secA-tanA)​

Answer 1

Step-by-step explanation:

i solve it step by step see the pic

Answer 2

Answer:

csA

Step-by-step explanation:

cosA/1+sinA+1-sinA/cosA

=cosA2+1-sin2/cosA(1+sinA)

# cosA2+cosA2/cos(1+sinA)

#2cosA2/cosA(1+sinA)

# 2cosA/1+sinA

# 2cosA/1+sinA*1-sinA/1-sinA

#2cosA(1-sinA)/cosA2

#2(secA-tanA)
