Question

prove that 1 minus cos theta divided by 1 + cos theta is equal to cosec theta minus cot theta whole square ​

Answer 1

Answer:

Step-by-step explanation:

1-cos Ф/1+cosФ

multiply both upside and downside by 1-cosФ

(1-cos)²/1-cos²Ф

1+cos²Ф+2cosФ/sin²Ф                (1-cos²Ф)=sin ²Ф

do partial division:-

1/sin²Ф+cos²Ф/sin²Ф-2cosФ/sin²Ф

cosec²Ф+cot²Ф+cosecФcotФ

(cosecФ+cotФ)²

lhs =rhs

hence proved
