Question

sec theta(1-sin theta) (sec theta+tan theta)=1

Answer 1

Answer:

1=1

Step-by-step explanation:

sec*(1-sin)=1/cos-sin/cos

and sec+tan= 1/cos + sin/cos

so when we multiply both (a-b)(a+b)=a^2-b^2

therefore,

(1/cos^2)-(sin/cos)^2

(1-sin^2)/cos^2

since, 1-sin^2=cos^2

so, cos^2/cos^2=1
