Question

(1 + tan square theta)(1- sin square theta)=_______​

Answer 1

Answer:

Step-by-step explanation:

(1+tansquare)(1-sinsquare theta )

(Secsquare)(cossquare theta)

I/cossquare(cossquare)

Cossquare cancelled from cos squre

We gget 1.

Formulae used above is.

Sec square theta =1+tansquare

1+sinsquare theta=cossquare

Secsquare=1/cos square

Here we go✌

Answer 2

Answer:

The answer is 1

Step-by-step explanation:

( 1 + tan²Ф) ( 1 - sin ²Ф)

we know that sec²Ф = 1 + tan²Ф and cos²Ф = 1 - sin²Ф

so substitute it and you get

sec²Ф x cos²Ф

1/cos²Ф x cos²Ф  because secФ = 1/cosФ

= 1

Hope this will help.
