Question

cos a - sina + 1 / cosa + sina - 1 = sec A + tan A

Answer 1

Answer:

Step-by-step explanation:

Cos@-Sin@ +1 ) /(Cos@+Sin@-1 )

1-Tan@ +Sec@/ 1+Tan@ -Sec@

1+( Sec@-Tan@) / 1-(Sec@-Tan@)

1/(Sec@-Tan@)

(Sec^2@ -Tan^2@)/ (Sec@-Tan@)

(Sec@ +Tan@)(Sec@-Tan@) / Sec@-Tan@)

Sec@+Tan@

LHS= RHS proved

---------------Formula used ------------

1= Sec^2@ -Tan^2@= (Sec@+Tan@)(Sec@-Tan@)

a/b = a+b/a-b

1= a. &. Sec@-Tan@ =b
