Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
आपल्याला 2tan2 45° + cos2 30° - sin2 60° चे मूल्यांकन करावे लागेल
वापरलेले सूत्र:
tan45° = 1
Cos30° = √3/2
Sin60° = √3/2
गणना:
2 tan2 45° + cos2 30° - sin2 60°
⇒ 2 × 12 + (√3/2)2 – (√3/2)2
⇒ 2 + 3/4 - 3/4
⇒ 2
∴ 2 tan2 45° + cos2 30° - sin2 60° चे मूल्य 2 आहे.
