Karnataka 1st PUC Basic Maths Question Bank Chapter 14 Standard Angles of Allied Angles<\/h2>\n

Question 1.
\nFind the value of
\n(i) cosec (-765\u00b0)
\n(ii) sec (-1305\u00b0)
\n(iii) sin 585\u00b0
\nAnswer:
\n(i) -cosec 765\u00b0
\n= -cosec (360x2<\/sup> + 45\u00b0)
\n= -cosec 45\u00b0
\n= – \u221a2<\/p>\n

(ii) sec (1305\u00b0)
\n= sec (360.3 + 225)
\n= sec 225\u00b0
\n= sec (180 + 45\u00b0)
\n= -sec 45\u00b0
\n= – \u221a2<\/p>\n

(iii) sin (360 + 225\u00b0)
\n= sin 225\u00b0
\n= sin (180 + 45\u00b0)
\n= – sin 45\u00b0
\n= – \u221a2<\/p>\n

Question 2.
\nEvaluate: \\(\\frac { 4 }{ 3 }\\)tan2<\/sup> 120\u00b0 + 3 sin2<\/sup> 300\u00b0 – 2cosec2<\/sup>240\u00b0- \\(\\frac { 3 }{ 4 }\\)cot2<\/sup> 60\u00b0
\nAnswer:
\nNow tan 120\u00b0 = tan (180\u00b0 – 60\u00b0)
\n= -tan 60\u00b0
\n= -\u221a3
\nsin 300\u00b0 = sin (360\u00b0 – 60\u00b0)
\n= – sin 60\u00b0 = \\(\\frac{-\\sqrt{3}}{2}\\)
\ncosec 240\u00b0 = cosec (180\u00b0 + 60\u00b0)
\n= – cosec 60\u00b0 = \\(\\frac{-2}{\\sqrt{3}}\\)
