Tricks to find maximum & minimum Values 90 – θ Formula

• sin (90° – θ) = cos θ
• cos (90° – θ) = sin θ
• tan (90° – θ) = cot θ
• cosec (90° – θ) = sec θ
• sec (90° – θ) = cosec θ
• cot (90° – θ) = tan θ

90 + θ Formula

• sin (90° + θ) = cos θ
• cos (90° + θ) = – sin θ
• tan (90° + θ) = – cot θ
• cosec (90° + θ) = sec θ
• sec (90° + θ) = – cosec θ
• cot (90° + θ) = – tan θ

If a cot θ + b cosec θ = m and a cosec θ + b cot θ = n If cot θ + cos θ = x and cot θ – cos θ = y If tan θ + sin θ = x and tan θ – sin θ = y Also Check – How to Prepare For Written Examination

Example: Maximum value of (2 sin θ + 3 cos θ) is

Solution:

Maximum value of 2 sin θ + 3 cos θ Example: The minimum value of 4 tan2 θ + 9 cot2 θ is equal to:

Solution:

Here, a = 9 and b = 4

Minimum value of a tan2 θ + b cot2 θ  Example: Find the value of tan 4° x tan 43° x tan 47° x tan 86°

Solution:

tan 4° x tan 43° x tan 47° x tan 86°

= tan 4° x tan 43° x tan (90° – 43°) x tan (90° – 4°)

[tan (90° – θ) = cot θ  and tan θ x cot θ = 1]

= tan 4° × tan 43° × cot 43° × cot 4°

= 1
