If the minimum value of (5\cos \theta-12\sin \theta) is (m), what is (m)?यदि (5\cos \theta-12\sin \theta) का न्यूनतम मान (m) है, तो (m) क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-13)(-13)
The amplitude is ( \sqrt{5^2+(-12)^2}=13), so the minimum is (-13). In exams maximum is positive amplitude and minimum is negative amplitude.Amplitude (\sqrt{5^2+(-12)^2}=13) है, इसलिए न्यूनतम (-13) होगा। परीक्षा में maximum positive और minimum negative amplitude होता है।
