1and manipal and eureka................d answer which manipal gave is correct it comes exactly 3.........10-3.9/2=6.1/2=3
i have some unsolved questions in inverse trigno..........posting here.......
Q1 Find range of values of a if sum of series \sum_{n=1}^{infinity}{(\frac{sec^{-1}\sqrt{\left|x \right|}+cosec^{-1}\sqrt{\left|x \right|}}{\pi a}})^{n}
is finite where \left|x \right|\geq 1;a>0

24tapan 11th ka bhi ans nahin hai mere paas.....[2][2] plz soln bataa......
24yup akand....i was telling manipal to recheck his soln so that he could correct his silly mistake.......but he didnt.[2]
21eure MERE BHAI thoda soch,
ITS VERYYYYYYYYYYYYYYYYYYYY easy.
sirf one-STEP ka sum hai........
baad me mein batata huun
21praji its 1/(2a-1) only c again
EURE dont read ahaed :
praji u may read:
r = 1/2a ; a = 1/2a
11WAISE I SUGGEST READERS NOT TO SOLVE THESE TYPE OF PROBLEMS AS THEY INVOLVE CALCULATOR WHICH IS PROHIBITED
24why are u using calculator...........u can use ur brain and calculate it.....[1][1]
11THEN WHY R U ASKING THE PROBLEMS IF U KNOW THEM HOW TO SOLVE[9][9][9][9][9][9][9][9][9][9][9][9][9][9]
1dont worry if u dont require such questions manipal der r people who need dis .....got it manipal.....[1][1][1].........dont be angry with me manipal ...itz a fact.....
24Q3 Ifcot^{-1}(\frac{n^{2}-10n+21.6}{\pi })>\frac{\pi }{6};n \varepsilon N
then find minimum value of n
24Q5easy ...bt still cant get it If a<1/32,then no. of soln. of (sin^{-1}x)^{3}+(cos^{-1}x)^{3}=a\pi ^{3}
24and matrix why sorry????????? u r trying to help me only............[1][1]
11Q 3 will never be asked in JEE as it contains approx but the sol is
24Q2Solve for x if [sin^{-1}cos^{-1}sin^{-1}tan^{-1}(x)]=1
where [.] denotes gint
