For an acute angle A, simplify √1 - ^2 A A .

A. 1 - ^2 A = ^2 A , and for an acute angle √ ^2 A = A . So the expression is A/ A = A . Answering A means the fraction was accidentally turned upside down.

For an acute angle A, simplify $\frac{1 - s i n ^{2} A}{s i n A}$ .

Class 10Trigonometric IdentitiesTrigonometry

A $tan A$
B $sec A$
C $cosec A$
D $cot A$

Step-by-Step Solution

1 - sin^{2} A = cos^{2} A

, and for an acute angle

cos^{2} A = cos A

. So the expression is

\frac{c o s A}{s i n A} = cot A

. Answering

tan A

means the fraction was accidentally turned upside down.

Answer: D)

cot A
