Answer 1

Answer:

rhs 1+sino/coso=1/coso+sino/coso=seco+tano

Answer 2

Answer:

The Answer is in the image!

Step-by-step explanation:

• Expand tan as sin/cos and sec as 1/cos.
• Make the denominator as cos by multiplying cos with 1 in the numerator.
• Cancel cos as both the denominators are cos.
• Thake '-' outside the bracket.
• Multiply the numerator and denominator with the conjugate.
• Use (a-b)^2 formula and (a)^2+(b)^2 formula for numerator and denominator respectively.
• Simplify.
• Replace sin^2 with 1-cos^2 in the denominator.
• Take '2' as a common outside the bracket.
• Take (1-cos) as common in the numerator.
• Cancel (1-cos) in numerator and denominator.
• Hence, (1+sin)/cos = RHS (Right Hand Side)
