−2sinxcosx=0 Step 5: Factoring the EquationWe can factor out the equation:2sinxcosx=0This implies:sinx=0orcosx=0 Step 6: Finding General Solutions1. For sinx=0: The general solution is: x=nπ,n∈Z 2. For cosx=0: The general solution is: x=π2+nπ,n∈Z Step 7: Conclusion...
Mathematics - General MathematicsA005In this paper, we investigate the one-variable equation, sinx+cosx+tanx+cotx+secx+cscx=n, where n is an integer. We prove that if n lies between(inclusively) -1 and 6; then the above equation has no real number solutions. While if n is greater than...
General solution：∫ sin^9(x) dx= -∫ sin^8(x) d(cosx)= -∫ (sin�0�5x)�6�6 d(cosx)= -∫ (1-cos�0�5x)�6�6 d(cosx)= -∫ (1-u�0�5)�6�6 du= -∫...
比如你不能用sinx^2+cosx^2=1去证明勾股定理。等你真要去证明一个很基础的定理的时候,你会发现很多工具都不能用了,因为那些工具都是基于这个定理推出的。就像别人要炼钢造大炮,钢不够,你说那还不简单,把现有的大炮融了炼钢啊?这是没意义的。另一方面,当时工具也没那么多,你怎么去证?不能脱离时代背景。就像...
