Principle of Mathematical Induction


In triangle ABC, if a = 18, b = 24, c = 30, find tan straight A over 2


Using  space space tan straight A over 2 space equals space square root of fraction numerator left parenthesis straight s minus straight b right parenthesis space left parenthesis straight s minus straight c right parenthesis over denominator straight s left parenthesis straight s minus straight a right parenthesis end fraction end root                                     ...(i)
Where s is the semi-perimeter of the triangle
Now,                        straight s equals fraction numerator 18 plus 24 plus 30 over denominator 2 end fraction equals 36
∴ From (i),  <pre>uncaught exception: <b>mkdir(): Permission denied (errno: 2) in /home/config_admin/public/ at line #56mkdir(): Permission denied</b><br /><br />in file: /home/config_admin/public/ line 56<br />#0 [internal function]: _hx_error_handler(2, 'mkdir(): Permis...', '/home/config_ad...', 56, Array)
