**Understanding complementary angles**

When solving the exercises of RS Aggarwal class 10 chapter 12 you will need to ensure that you never forget the following :

tan (90°- A) = cot A | cot (90°- A) = tan A |

sec (90°- A) = csc A | csc (90°- A) = sec A |

sin (90°- A) = cos A | cos (90°- A) = sin A |

The above equations can be referred to while solving the problems for chapter 12 of RS Aggarwal Class 10 Maths. However, to ensure that you do not forget them we would suggest that you regularly practise the problems and peruse the solutions for RS Aggarwal on our website
