12sin X + 5cos X
অনুসৃত ধারণা:
একটি sinθ + b cosθ এর সর্বনিম্ন মান = -√(a2 + b2)
একটি sinθ + b cosθ এর সর্বোচ্চ মান = √(a2 + b2)
গণনা:
12sin X + 5cos X এর সর্বোচ্চ মান = -√(a2 + b2)
⇒ -√(122 + 52)
⇒ -13
12sin X + 5cos X এর সর্বোচ্চ মান = √(a2 + b2)
⇒ √(122 + 52)
⇒ 13
∴ 12sin X + 5cos X- এর সর্বনিম্ন এবং সর্বোচ্চ মান যথাক্রমে -13 এবং 13
