=1/cosecA-cotA+1/cosecA+cotA.                    =cosecA+cotA+cosecA-cotA/cosec*2A-cot*2A.                                                                 =2cosecA/1.                                                        =2(1/sinA)                                                            =2/sinA.

ARE YOU IN NEED OF HELP TO SOLVE YOUR INFERTILITY PROBLEM OR GET PREGNANT? contact Dr. LUCAS Miracle Center on this email (miraculouscentre @gmail .com).  I'm Wright Eva from the USA, I have been trying to get pregnant for 6 years and I needed help! I have been to different hospitals and Doctors. The doctors always say that my husband and I are fine and I don't know where else to turn. Until one day an old friend introduced me to this great spell caster who helped her to get her lost husband back with a love spell and also made her pregnant, So I decided to contact this spell caster Dr. Lucas through his private What's App Number +15302120104, after interaction with him he instructed me on what to do, after then i should have sex with the my husband or any man I love in this world, And i did so, within the next one months i went for a check up and my doctor confirmed that i am 2 weeks pregnant with two babies. I am so happy!! If you also need help to get pregnant or need your ex back then contact through his private What's App Number +15302120104.
