" पश्न 9."(1+sin theta)/(cos0)+(cos theta)/(1+sin0)=2sec0

Prove : (cos theta)/(1+sin theta) + (cos theta)/(1-sin theta)= 2 sec theta

If (sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)=4/sqrt3, 0^@ < theta <90^@ , then the value of (tan theta+sec theta)^-1 is:

Show that (1 + sin theta)/ cos theta + cos theta / (1 + sin theta) = 2 sec theta

Prove :(cos theta)/(1+sin theta)+(cos theta)/(1-sin theta)=2sec theta

Prove the following identities: (cos theta)/(1-sin theta)+(cos theta)/(1+sin theta)=2sec theta

Prove that :(sin theta cos(90^(0)-theta)cos theta)/(sin(90^(0)-theta))+(cos theta sin(90^(0)-theta)sin theta)/(cos(90^(@)-theta))=1csc^(2)(90^(@)-theta)-tan^(2)theta=cos^(2)(90^(@)-theta)+cos^(2)theta

If (cos theta )/(1-sin theta )+(cos theta )/(1+sin theta )=4, 0^@ यदि (cos theta )/(1-sin theta )+(cos theta )/(1+sin theta )=4, 0^@< theta<90^@ , है, तो (tan theta+ cosec theta) का मान क्या होगा ?

If (cos theta_(1))/(cos theta_(2))+(sin theta_(1))/(sin theta_(2))=(cos theta_(0))/(cos theta_(2))+(sin theta_(0))/(sin theta_(2))=1 , where theta_(1) and theta_(0) do not differ by can even multiple of pi , prove that (cos theta_(1)*cos theta_(0))/(cos^( 2)theta_(2))+(sin theta_(1)*sin theta_(0))/(sin^(2) theta_(2))=-1

If (cos theta_(1))/(cos theta_(2))+(sin theta_(1))/(sin theta_(2))=(cos theta_(0))/(cos theta_(2))+(sin theta_(0))/(sin theta_(2))=1 , where theta_(1) and theta_(0) do not differ by can even multiple of pi , prove that (cos theta_(1)*cos theta_(0))/(cos^( 2)theta_(2))+(sin theta_(1)*sin theta_(0))/(sin^(2) theta_(2))=-1
