Algebra.Com's Answer #853518 by CPhill(2189) You can put this solution on YOUR website! It appears there are a few typos in your expression. Based on standard trigonometric shorthand, I will interpret your equation as:\r \n" ); document.write( "\n" ); document.write( "If \"csn\" was meant to be **** and \"tan2\" meant ****, we can solve it as follows:\r \n" ); document.write( "\n" ); document.write( "### 1. Simplify the Trigonometric Terms\r \n" ); document.write( "\n" ); document.write( "First, let's rewrite everything in terms of and to see if the expression simplifies.\r \n" ); document.write( "\n" ); document.write( "* \n" ); document.write( "* \r \n" ); document.write( "\n" ); document.write( "Now, substitute these back into the equation:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "### 2. Find a Common Denominator\r \n" ); document.write( "\n" ); document.write( "Since , the equation becomes:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "### 3. Solve for \r \n" ); document.write( "\n" ); document.write( "This is a transcendental equation, which usually requires numerical methods or a graphing calculator to solve precisely. However, we can test small values since is close to zero.\r \n" ); document.write( "\n" ); document.write( "If we let :\r \n" ); document.write( "\n" ); document.write( "* If , then . \n" ); document.write( "* Since the result is slightly negative (), must be a small negative angle.\r \n" ); document.write( "\n" ); document.write( "Using the small-angle approximation where and :\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Using the quadratic formula :\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "### 4.
